Question

the length of a rectangle is 1cm more than the breadth. if the length is increased by 3 cm and breadth by 2 cm, the area is increased by 38 cm2. find the original dimensions of the rectangle.
solve step by step​

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.
