Question : 7

Total: 50

Calculate the area of the farmland.

0.32ha
0.36ha
0.47ha
0.52ha

Solution:

Concept:

The farmland is a trapezium, so find its area using the trapezium formula and convert

\text{m}^2

to hectares.

Explanation:

From the diagram, the parallel sides are

100

m and

60

m, and the perpendicular height is

40

m.

Area of trapezium

= \frac{1}{2} \times (\text{sum of parallel sides}) \times \text{height}

\text{Area} = \frac{1}{2} \times (100 + 60) \times 40

\text{Area} = \frac{1}{2} \times 160 \times 40 = 3200\ \text{m}^2

Since

1\ \text{ha} = 10{,}000\ \text{m}^2

, convert:

\frac{3200}{10{,}000} = 0.32\ \text{ha}

Answer:

A.

0.32

ha
