Question 126 (a) (i)

Architects design many types of buildings. They draw plans for houses, such as the plan shown in the following figure.

An architect wants to install a decorative moulding around the ceilings in the rooms. The decorative moulding costs Rs. 500/ meter.

Find how much moulding will be needed for the family room.

Answer 1

Given, breadth of the family room = 5.48 m

and length of the family room = 4.57 m

$\therefore$ Perimeter of the family room = 2(Length + Breadth) = 2(5.48 + 4.57)

= 2 $\times$ 10.05 = 20.10 m
