Question

Four planks of wood each of length 2 m and breadth 1.1 m are to be painted on both side.
Determine the cost of painting at the rate of 4.50
per square metre.​

Answer 1

Answer:

The total area to be painted is 19.2 sq.m.

Step-by-step explanation:

Length of wood plank = 2 m

Breadth of wood plank = 1.2 m

Area of wood plank =Length \times Breadth = 2 \times 1.2 = 2.4 sq.m.Length×Breadth=2×1.2=2.4sq.m.

Area of both sides of wood plank = 2 \times 2.4 = 4.8 sq.m.2×2.4=4.8sq.m.

Area of 4 wood plank = 4.8 \times 4 = 19.2 sq.m.4.8×4=19.2sq.m.

Hence the total area to be painted is 19.2 sq.m.
