# 12 m² is the area of

(a) a square with side 12 m

(b) 12 squares with side 1 m each

(c) 3 squares with side 4 m each

(d) 4 squares with side 3 m each

**Solution:**

We have to find which of the given options represents the area of 12 m²

- a) a square with side 12 m

Area of square = (side)²

= (12)²

= 144 m²

Therefore, option a is false

- b) 12 squares with side 1 m each

Area of square = (side)²

= (1)²

= 1 m²

Area of 12 squares = 12(1) = 12 m²

Therefore, option b is true

- c) 3 squares with side 4 m each

Area of square = (side)²

= (4)²

= 16 m²

Area of 3 squares = 3(16) = 48 m²

Therefore, option c is false

- d) 4 squares with side 3 m each

Area of square = (side)²

= (3)²

= 9 m²

Area of 4 squares = 4(9) = 36 m²

Therefore, option d is false&
