Question

4. A wall is 12 m long and 4 m high.
There is a rectangular window E
measuring 2.5 m by 2 m in the
wall. Find how much it will cost
to paint the wall at the rate of 22 per sq. m.​

Answer 1

Answer:

Length of wall = 12 m and Hight = 4 m

area = length * height

12*4

=48m^2

now area of window = length * height

2.5*2

=5m^2

now area of wall = area of wall - area of window

= (48-5)

= 43m^2

cost of painting =43*22

=946
