Question

A Rod of length 20 metre is bent to make a rectangle. If its length is 2 more than breadth, find its length and breadth


​

Answer 1

perimeter = 20 m

l = 2+b

peri = 2(l+b)

2(2+b+b) = 20

2+b+b = 10

2b + 2 = 10

2b = 10-2

2b = 8

b = 4

l = b+2

= 4+2

=6 m

length = 6 m

breadth = 4 m
