Step-by-step explanation:
Dimensions of room;
l = 5m , b= 4m
Dimensions of square carpet;
l = 1.2 m
(a) area covered by carpet
= l*l = 1.2 * 1.2 = 1.44 m^2
(b) area of floor
= l * b = 5*4 = 20 m^2
(c) area of floor which is not carpeted
= area of room - area covered by carpet
= 20 - 1.44 = 18.56 m^2.
(d) square meters of carpet required to cover the floor of room = area of room
= 20m^2
