increased by 9 cm and the breadth is reduced by 5 cm, the area remains the same.
Find the dimensions of the rectangle.
​

Answer 1

Answer:

l=b+3 , a=l*b

Step-by-step explanation:

If L+9 * B-5 = Same area

then,

L+9 * L-3-5 = same area

L+9 * L-8 = l * l-3

$l^{2}$ -8l +9l -72 = $l^{2}$ -3l

L-72 = -3l

4L = 72

l = 18

therefore,

L=18

B=L-3 = 15
