Question

1) The figure at the top is a parallelogram; the area is A = bh; where b is the base and h is the height; use properties of special right triangles to find h, and the area of the parallelogram

a) Read the problem once and state what is the problem about?

Answer 1

`10 √(3) {cm}^(2)`

Explanation:

The area of a parallelogram is A=bh.

From the diagram, the base is b=5m

We now use the properties of 30°-60°-90° right angle to find h.

The sides of this triangle is given by x,½x,½x√3

Where x is 4

Therefore we have 4,2, 2√3

So we have h=2√3m

The area now is

`A = 5 * 2 √(3) = 10 √(3) {cm}^(2)`

a)The problem is about finding area of a plane figure
