Question

find the cost of painting a wall having a door of dimension 4m ×3m the length and breadth of the wall are 10m and 10m respectively and the rate of painting is rupees 50 per m2​

Answer 1

Answer:

4400 rs.

Step-by-step explanation:

First,

the area of the wall= 10*10=100 m²

the area of the door=4*3= 12 m²

subtracting the door's area from the wall's area

we have 88 m² as the area of the part which we want to paint

the cost of painting for 1 m²= 50 rs.

the cost of painting for 88 m²= 50*88 rs.=4400 rs.

Hope This Helps!!!

Answer 2

Answer:

Area of door = 4×3

12m²

Area of the wall = 10×10

100m²

Area of the wall without door =100-12

88m²

Cost = 88×50
