Question

if the perimeter of the square is 400 cm .. find its area

Answer 1

HEYA MATE

lets start

first of all perimeter = 4 × side

then the side = 4 ÷ perimeter

so to find the length of the square is 4 ÷ 400

that is 100

now we got the cm of one side is 100

now to find the area

for finding the are the formula is side×side

100×100

=10000

so the area of the square is 10000
