Answer 1

Answer:

22500

Step-by-step explanation:

door area= 3*2 = 6 m2

window area= 2*2 = 4 m2

total = 10 m2

wall area = 10*10 = 100 m2

left area for painting = 100 - 10 = 90 m2

total cost = 90*250 = 22500

Answer 2

area of door=3m×2m

=6m²

area of 3 windows=3(2×2)

3×4

12m²

area of wall=10×10

100m²

to find the area of wall ti be painted

100-(6+12)

100-18

82m²

rate of painting=250

82×250

20500 rupees.
