Question

find the perimeter of rectangle if area is 72msq and length of rectangle 12 m

Answer 1

Hey dear your answer is here....

Given:-

Length of rectangle l =12m

Area=72msq

we know:-

Area of rectangle=l*b

72=12*b

b=6cm

And,

Perimeter of rectangle=2[l+b]

P=2[12+6]

P=2*18

P=36cm

So,
the perimeter of rectangle is 36cm.

Thnks

Answer 2

Length*Breadth=72 m²

Breadth=72/12=6 m

Perimeter=2(Length+Breadth)=2(12+6)=36 m
