Answer:

P = 25.6 feet

Explanation:

Given that,

Rectangle A and B have the same Area.

The area of a rectangle is given by :

A = lb


l_Ab_A=l_Bb_B

We have,


l_A=7\ m, b_A=4\ m, b_B=10\ m

So,


l_B=(l_Ab_A)/(l_B)\\\\l_B=(7* 4)/(10)\\\\l_B=2.8\ m

The perimeter of rectangle B,


P=2(l_B+b_B)\\\\=2(2.8+10)\\\\=25.6\ ft

So, the perimeter of rectangle B is equal to 25.6 feet.
