Question

Find the area of a square room whose perimeter is 34m.

Answer 1

Answer:

Perimeter of square = 4a

34 = 4a

a = 8.5m

Hence, side is 8.5m

Now,

Area = a^2 = 8.5^2 = 72.25 sq.m

Answer 2

Perimeter of square room (cube) = 34m

Let side of the square room be X m.

12X = 34 m

X = 34/12 m

X = 2.83 m (approx)

Therefore, side of the square room/cube = 2.83 m

Area of square room = 6 × side^2

Area of the square room = 6×2.83 m^2

Therefore, area of the square room = 16.98m^2
