Question

An interior decorator bought a piece of cloth 2.6m by 3m. Estimate how many pieces he will buy to cover a wall of 195m2.

Answer 1

Dimensions of cloth = 2.6m by 3m

So, Area of cloth = 2.6*3

= 7.8 m²

To cover the entire wall of 195m², he will need

(Wall Area)/(Cloth Area) pieces of cloth

= 195m²/7.8m²

= 25

So, he will need 25 such pieces to cover the entire wall.

Hope this helped!
