Area of a square of side 6 m is equal to the area of ______ squares of each side 1 cm.
Solution
Area of a square of side 6 m is equal to the area of 360000 squares of each side 1 cm.
Explanation:
Let number of squares having side 1 cm = x
According to the question,
Area of side 6 m square = Area of side 1 cm square ......[∵ area of square = (side)2]
∴ (6 m)2 = x × (1 cm)2 ......[∵ 1 m = 100 cm]
⇒ (600 cm)2 = x × (1 cm)2
⇒ 360000 cm2 = x cm2
⇒ x = 360000
