Question

A wooden sheet is 15 m long and 6 m board. It has to be painted on both sides. Find the cost of painted at 30 per square metre

Answer 1

ANSWER:

5400 UNITS

SOLUTION:

AREA OF SHEET =15 × 6

= 90 m^2

SINCE PAINT IS DONE ON TWO SIDES

THEREFORE,

AREA TO BE PAINTED = 2×90

= 180 m^2

COST = 30 /m^2

THEREFORE , COST OF PAINTING BOTH SIDES

= 30×180

=5400 UNITS
