Question

Find the cost of painting a wall of length 5m 10cm and breadth
4m 25cm long if the rate of painting is ₹10 per m2
.

Answer 1

Answer :-

if we want to find the cost of painting we have to convert the m to cm

1 m = 100 cm

5 m 10 cm = 510 cm

4m 25 cm = 425 cm

we have to find the area

(Length × Breadth

510 × 425

= 216750 sq . cm

now convert it into m 216750 ÷ 100 =2167 sq.m

if 1 m = 10

then 2167

= 2167 × 10

= 21670 Rs

Therefore,₹21670 is needed to paint the whole wall
