Area of a square photo frame is 144cm²

To find:

perimeter of the photo fame,

Solution:

Area of Square = Side × Side

Given that area of plot is 144

$144 = {S}^{2}$

$\sqrt{144} = S$

$12 = S$

Side = 12

We know that perimeter of Square

$perimeter \: of \: Square = 4 \times s$

$perimeter \: of \: Square = 4 \times s$

$perimeter \: of \: Square \: = 4 \times 12$

$perimeter \: of \: Square = 48$

Hence the perimeter of the photo fame 48
