Area
Today for Maths we had to find the area, perimeter, labour cost, cost per square meter and GST of a shape for a shade sail that was split into a rectangle and a triangle.
1, Find the area of shape 1 (Rectangle)
9 x 5
= 45 sq meters
2, Find the area of shape 2 (Triangle)
5 x 5
=25 ÷ 2
= 12.5 sq meters
3, Add together the are of shape 1 and 2 to find the total area
45 + 12.5
= 57.5 sq meters
4, Add together the length of each side to find the total perimeter
9 + 5 + 14 + 7
= 35 m
5, Find the cost of labour ($25.60 per hour for 4 hours)
4 x 25.60
= $102.4
6, Find the price of fabric ($8.95 per sq meter)
8.95 x 57.5
= $514.62
7, Find the cost of labour + fabric
103.4 + 514.62
= $ 617.02
8, Find GST on its own
617.02 x 0.15
= $92.55
9, Total price with GST
617.02 + 92.55
= $709.57
