Question

A verandah of width 2.25 m is constructed all along outside a room which is 5.5 m long and 4 m wide find the area of the verandah.

Answer 1

Question 5: A path of 1m width is built along the border and inside a square garden of side 30m. Find:
(i) the area of the path
(ii) the cost of planting grass in the remaining portion of the garden at the rate of Rs 40 per m2.



Solution: Given, side of the garden = 30m, Width of the path inside the garden = 1m, Cost of the planting of grass = Rs 40 per m2.

Therefore, side of the garden without path = 30m — 1m — 1m = 28m

Area of square = Side2
Area of square garden 
= (30m)2 = 900 m2

Area of garden without path 
= (28m)2 = 784 m2

Area of path = Area of garden — Area of garden without path = 900m2 —784m2 = 116 m2

Cost of planting grass in the remaining portion of garden = Rate × Area
= Rs 40 × 784 = Rs 31360

Answer 2

◆Hey There◆

It is in our book

Area of verandah = Area of outer figure - Area of inner figure

Area of outer figure = (5.5 + 2.25 + 2.25) x (4 + 2.25 + 2.25)

= 10 x 8.5

= 85 m2

Area of inner figure = 5.5 x 4

= 22 m2

Area of verandah = 85 - 22

= 63 m2

Cost = 63 x 200

=. 12,600
