Question

the length of a rectangle exceeds its breadth by 3cm. if the length and breadth are are each increased by 4 cm ,the perimeter of the new rectangle will be 22 cm more than half the perimeter of the given rectangle then find the ratio of length to breadth of the rectangle

Answer 1

Answer:

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.
