Question 54 Perimeter and Area - Exercise

The area of a square of side 6 m is equal to the area of ____________squares of each side 1 cm

Answer:

The area of a square of side 6 m is equal to the area of 3,60,000 squares of each side 1 cm.

Let us assume the number of squares having a side of 1 cm be ‘x’.

As per the condition in the question,

Area of the side 6 m square = Area of side 1 cm square

(6m)2 = x(1cm)2

360000 cm2 = x cm2 … [[because 1 m = 100 cm]]

x = 360000cm2/1 cm2

x = 36000
