Question

Two and half litres of paint is used to cover 725 sq m of area. Step by Step

1. How much will be required to paint 2001 sq m of area ?

2. How much area is sq m can be coCeres by 4.75 litres of paint ?​

Answer 1

Step-by-step explanation:

1) Area covered by 2/½ l(5/2l)= 725 m²

Let Paint required to cover 2001 m²= y

Since it is direct proportion

x/y= x/y

≈ 725/5/2= 2001/y

≈ 725×2/5= 2001/y

≈ 290/2001= 1/y

≈2001/290= y

≈ 6.9 lit

2) Let area covered by 4.75 lit be x

As it is direct proportion

≈ x/y=x/y

≈ 725/5/2= x/ 4.75

≈ 290×4.75= x

≈ 1337.5 m²= x
