Question

The length and breadth of a rectangle are in the ratio of 4:3.if the length is reduced by 3cm and breadth is increased by 3cm ,it become a square if the length is x, what is the breadth​

Answer 1

Step-by-step explanation:

Let b be the breadth

length =b+3

If length and breadth increased by 2cm new area is 70 sq cm more

i.e., b(b+3)+70=(b+2)(b+5)

b

2

+3b+70=b

2

+2b+5b+10

4b=60

b=15

l=15+3=18.
