Question

perimeter is 320m what is its area
$320 = 4 \times side$
$side = 320 \div 4$

Answer 1

320 ÷ 4 = 80 m. Area of Square = Side2 = 802 = 6400 sq m. Question 3: Find the breadth of a rectangular plot of land, if its area is 440m2 and the length is 22m. Also find its perimeter.

Answer 2

Hi!

Seems like the question is incomplete as you didn't tell whether it's a square or its rectangle or any other figure, but still, from given hints, it seems like it's a square. So here is your answer -:

Perimeter= 320m
Side=?

Perimeter of square= 4×side
320=4×side
side=320/4
side= 80m

Now,

Area of square= Side×Side
= 80×80
=6400m^2


Hope it helps...!!!
