Answer 2

Greetings..!!

Given Perimeter of square = 80 m .

Formula for perimeter of square = 4 * Side

Let the side be x meters.

⇒x*4=80

⇒x=80/4 {transposing 4 to R.H.S}

⇒x = 20 m

So, length of square is 20 m .

∴ Area of square = Side² = 20² = 20*20 = 400 m².

Answer : Hence, area of the given square is 400 m².
