Question

find perimeter of rectangle whose length is 12 cm and breadth is 7 cm
explain step by step.

Answer 1

We know that
Perimeter of rectangle= 2(Length+Breadth)
So perimeter of rectangle=2×(12+7)=2×19=38cm

Answer 2

length of the rectangle =12cm
breadth of the rectangle =7cm
perimeter of the rectangle =2(l+b)
=2(12+7)
=2(19)
=38
