Question

In a rectangle if length is increased by 7 units & breadth is decreased by 3 units or if length is decreased by 7 units & breadth is increased by 5 units, in both the cases the area remains same. Find the dimensions of the rectangle. Also find the area of the rectangle.​

Answer 1

Answer:

Assume, Length= x units

Breadth= y units

by problem,

(x+7)(y-3)=(x-7)(y+5) ......(1)

(x+7)(y-3)= xy .......(2)

solving 1 & 2

x=28

y=15

area of rectangle=28*15=420 square units

Dimension=2( x+ y)=2(15+28)=86 units
