Answer 1

✰✰|| Given ||✰✰

• length of room = 15m

• width of room = 8m

• side of carpet = 6m

✰✰|| To Find ||✰✰

• area of room

• area of carpet

• area of room not carpeted

✪|| Solution ||✪

area of room = length × breadth

→ area of room = 15m × 8m

→ area of room = $\bold{{120m}^{2}}$

area of carpet = side × side

→ area of carpet = 6m × 6m

→ area of carpet = $\bold{{36m}^{2}}$

area of floor not carpeted = $\bold{{120m}^{2} - {36m}^{2}}$

→ area of carpet not carpeted = $\bold{{80m}^{2}}$

Area of floor nor carpeted is

80sq m
