Question

10, A room has rectangular floor of size 300 m by
200 m. A square carpet of side 180 m is laid in
the room. Find the area of floor which is not
carpeted.​

Answer 1

SolutioN :-

Length of floor = 300 m

Breadth of floor = 200 m

★ Area of floor = L × B

→ 300 × 200

→ 60000 m²

Side of carpet = 180 m

★ Area of carpet = a²

→ 180 × 180

→ 32400 m²

Area of floor with not carpeted = Area of floor - Area of carpet

→ 60000 - 32400

→ 27600 m²

∴ Area of floor not carpeted is 27600 m²

Answer 2

$\large{\underbrace{\sf{\pink{Required \:answer:}}}}$

⟶Length of floor =300 m

⟶Breadth of floor = 200 m

• Area of floor = L× B

⟶300×200

$60000 {m}^{2}$

⟶Side of carpet= 180 m

$area \: of \: carpet \: = {a}^{2}$

⟶180×180

$32400 {m}^{2}$

Area of floor with not carpeted = Area of floor- Area of carpet

⟶60000-32400

$27600 {m}^{2}$
