Answer 1

Answer:

HEY THERE !!

HERE IS YOUR ANSWER..

Step-by-step explanation:

area of door = length×breadth

= 2.5 × 1

= 2.5 m²

area of wall = length× breadth

= 3.5 × 2.8

= 9.8 m²

total area for white washing = area of wall - area of door

= 9.8 - 2.5

= 7.3 m²

so, 7.3 m² of area will be white washed.

1m² = 25

7.3 m² = 25 × 7.3

= 182.5 rupees

cost of White washing of the wall is rupees 182.5.
