Question

A door of dimensions 3m*2m is on the wall of dimensions 10m*10m. Find the cost of painting the wall if rate of painting is Rs 2.50 per sq.m.

Answer 1

Answer:

SO IT TAKES 94*2.50=235 RS TO PAINT THE WALL.

Answer 2

Answer:

Cost of painting is Rs. 235

Step-by-step explanation:

Dimensions of the wall is 10m*10m

Hence, area of the wall is (10×10) = 100 m²

Dimensions of the door is 3m*2m

Hence, area of the door is (3×2) = 6 m²

Hence, area of the wall without the door is (100-6) = 94 m²

Rate of painting is Rs. 2.50 per sq. m

Hence, total cost of painting is (94×2.50) = 235
