Answer:

10 \sqrt{3}  {cm}^{2}

Step-by-step 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 \times 2 \sqrt{3}  = 10 \sqrt{3}  {cm}^{2}

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