Question

Given the perimeter of the square floor of a hall is 82m ,find the area of the floor of the hall.

Answer 1

Answer:

First of all we have to find sides of square

Side of square= Perimeter÷4=82m ÷ 4= 20.5m

Area of square=Side×Side= 20.5m×20.5m =41m

Area of floor is 41m²

Answer 2

Answer:

1681/4m^2

Step-by-step explanation:

formula to find perimeter= 4a

4a=82

a=82/4=41/2= length of one side

AREA= a^2

41/2^2= 41 x 41/ 2 x 2=

= 1681/4m^2
