2. the length of a rectangle is increased by 10%, while its width is increased by 20%. by how many percent is the area of the rectangle enlarged?
luas = p*l
luas' = (p+10%)*(l+20%)
misal : p=2cm l= 1cm
luas = 2*1 = 2 cm^2
luas'= (2+10%)*(1+20%)
=2,2*1,2
=2,64 cm^2
pertambahan luas = 0,64 cm^2 = 32%

3. 11 A rectangle has sides which differ in length by 3 cm. If the area of the rectangle is 154 cm, find its perimeter.
Jangan dihapus.
l = length
is 3 cm longer than the w = width
Therefore
l = 3 + w
Area (a) = 154 cm²
--------------------------
Therefore
a = l · w
a = (3+w )·w
154 = w(3+w)
154 = 3w + w²
w² + 3w - 154 = 0
(w+14)(w-11) = 0
w ≠ -14
Therefore
w = 11 cm
---------------------------
Find the length (l)
l = 3 + w
l = 3 + 11
l = 14 cm
---------------------------
Find the perimeter
P = 2(l+w)
P = 2(14+11)
P = 2(25) = 50 cm
Perimeter = 50 cm

5. a rectangle measured 12/5 m by 10/9m. Find the area of the rectangle. Put the answer in the mixed number in its simplest from.
Jawaban:
Jawaban ada di penjelasan.
Penjelasan dengan langkah-langkah:
Karena area/luas, maka dikalikan lebar dengan panjang. 12/5 × 10/9 hasilnya 120/45. Diubah menjadi pecahan teratur sebelum disederhanakan; hasilnya 2 30/45. Disederhanakan menjadi 2 2/3.
6. Paul had a square piece of paper. He cut out a rectangle that was 4 centimeters by 9 centimeters. The area of the left over paper was 108 square centimeters. What was the length of the sides of Paul's original sauare?
Penjelasan:
Diketahui persegi panjang yg diptoong keluar sebesar 4x9 cm
Sisa kertas 108cm^2
Cari panjang kertas awal
pertama cari luas kertas potongan
=4x9 =36 cm^2
Luas awal = 108 + 36 = 144 cm^2
Dikatakan itu square pas awalnya maka
S^2 = ✓144 = 12
So, the length of the sides of Paul's original square is 12 centimeter

8. The length of a rectangle exceeds its width by 2 cm. If each dimension were increased by 3 cm, the area would be increased by 51 cm2. The width of original rectangle is equal to……………
Jawab:
6 cm
Penjelasan dengan langkah-langkah:
Misalkan panjang (length) sebagai x, dan lebar (width) sebagai y
i. x=y+2
ii. (x+3)(y+3)=xy+51
y=?
Dari persamaan ii. bisa diperoleh(x+3)(y+3)=xy+51
xy+3x+3y+9=xy+51
3x+3y=42
x+y=14 ... iii.
Substitusi persamaan i. ke persamaan iii.(y+2)+y=14
2y=12
y=6
Diperoleh lebar 6cm

12. The length of a rectangle exceeds its width by 2 cm. If each dimension were increased by 3 cm, the area would be increased by 51 cm2. The width of original rectangle is equal to
The original width of the rectangle is equal to 6 cm.
[tex]\\[/tex]
Pembahasan(Explanation)
We know that from the problem,
the length (l) of the rectangle exceeds its width (w) by 2 cm, so the length of the rectangle is width + 2or w + 2,each dimension of the rectangle were increased by 3 cm so that the area would be increased by 51 cm², andthe new area of the rectangle minus the original area of the rectangle would be 51 cm².The area of a rectangle is equal to the length multiplied by the width. Since the length of the rectangle exceeds its width by 2 cm, we can express the original area of the rectangle as OA = w(w + 2) where OA is the original area of the rectangle.
The new area of the rectangle is equal to the original area of the rectangle plus 51 cm² when each dimension of the original area is increased by 3 cm; we can express this as NA = (w + 3)(w + 2 + 3) or NA = (w + 3)(w + 5) where NA is the new area of the rectangle.
By using the information we got before, we can find the original width of the rectangle as follows.
NA - OA = 51 cm²
(w + 3)(w + 5) - w(w + 2) = 51
w² + 5w + 3w + 15 - w² - 2w = 51
w² - w² + 5w + 3w - 2w + 15 = 51
6w + 15 = 51
6w = 51 - 15
6w = 36
w = 36/6
w = 6
Therefore, the original width of the rectangle is equal to 6 cm.
