Question

A rod 86 cm long is bent in the form of a rectangle such that its length is 7 cm greater than its breadth its length and breadth are ____ respectively​

Answer 1

Answer:

Step-by-step explanation:

Let b be x  

Therefore l=x+7

Perimeter = 2(l+b)

86=2(x+7+x)

86=2(2x+7)

86=4x+14

4x=72

X=18

B=18

L=25

Area=lb

=18*25

=450
