Question

Tony is laying out the design for a concrete path.

The path is to be L-shaped as shown in the plan. The measurements are in millimetres.
Tony has to buy reinforcing mesh
He needs to calculate the area of the path
What is the area of the path in square metres (m)?
square metres (m)
1200
4000
1200
6200

Answer 1

Area of shape = 10.8 m²

Explanation:

Given:

Length of rectangle 1 = 4000 mm = 4 m

Width of rectangle 1 = 1200 mm = 1.2 m

Length of rectangle 2 = [6200-1200] mm = 5 m

Width of rectangle 2 = 1200 mm = 1.2 m

Find:

Area of shape

Computation:

Area of shape = Area of rectangle 1 + Area of rectangle 2

Area of shape = [(4)(1.2)] + [(5)(1.2)]

Area of shape = 4.8 + 6

Area of shape = 10.8 m²
