Question

The perimeter of a square is equal to 80 m. Its area is
i. 20 m
ii. 40 m
iii. 400 m
iv. 400 m​

Answer 1

400m

as area is side * side

perimeter given is 80 m  which is equal to 4 * side

to find the side we will divide 80 by 4

side will come out to be 20 m

now area is side * side which will be equal to 20*20=400m

Answer 2

Answer: iv. 400 m​

Step-by-step explanation:

the figure is a square so we divide 80 by 4 as all the sides are equal to get lenght of all sides

80 divded by four = 20

now to find the area we sqare the lenght which is equal to 20 x 20 = 400m thus the answer = 400
