Question

A wall in Anita's house to be painted. The wall is 7 cm
long and 5m high. If the painter changes 120
rupees per square metre, how much will she
have to be pay?​

Answer 1

Answer:

length=7cm

height=5m

change 7cm into m

7÷100m

14m (1m=100cm)

area=l×b

=14×5m

70m²

painter charged per metre square=120×70

=8,400 rupees

Answer 2

length - 7cm

hight - 5x100=500cm

charge per square meter = 120

therefore,

Lxhx2= 7x500x2 = 7000cm

7000/100=70meter

so, 70x120= 8400 ans
