Question

find the side of square were perimeter 360m area 441cm square solve them

Answer 1

Therefore
Area = 441 cm ^2
Side ^2= 441cm^2
Side = 21 cm ( answer)
Second case
Perimeter = 360marea
4*side= 360
Side= 360/4
Side = 90 ( answer)

Answer 2

In this, you can either use the area or perimeter to find the side.

With area,

Area of a square = (side)^2
441cm^2 = (s)^2
s = square root of 441cm
s = 21cm

The side = 21cm

With perimeter,

Perimeter = 4 (side)
360m = 4 (side)
360m ÷ 4 = side
90m = side
9000cm = side
side = 9000cm

But you will get different answer if the perimeter and area are not correct for the square.
