From the figure, we see that the garden measures 20m x 20m

Area = L × B = 20m × 20m = 400m²

(ii) Varandah measures 10m x 5m.

Total Area of Varandah = L × B = 10m × 5m = 50m²

Cost per square meter = Rs. 30

If 1 m² costs Rs. 30

50m² costs Rs. 50 × 30 = Rs. 1500

(iii) Length of the reading room = 5m

Breadth of the reading room = 6m

As,

Area of rectangle = length × breadth

Area of floor of his room = 5 × 6 = 30 m²

Area of one tile = length × breadth

= 25 cm × 25 cm

= 0.25 m × 0.25m

= 0.0625 m²
