Question

What is the area of this figure?

Answer 1

A = 90km2

Explanation:

Area of a rhombus is:

1. A = s x h (if given side and height)

2. A = 1/2 a x b (if given lengths of diagonals)

3. A = s^2 sin A (if given side and length)

Therefore from your problem, height and side is given thus, you'll use number 1

A = s x h

A = 9km x 10km = 90km2

Answer 2

90km² only if it is parallelogram

Explanation:

base = 9km

height=10km

area of parallelogram = b x h

=9km x 10km

=90km²
