Answer:
The answer to your question is:
a) 33 u²
b) 30 u²
Explanation:
a)
Here there is a rectangle and 2 triangles
Rectangle area = base x height
= 7 x 3
= 21 units²
Triangle area = (base x height) / 2
= 4 x 3 / 2
= 12/2
= 6 units²
Total area = 21 + 6 + 6
= 33 units²
b)
Rombus area = base x height
= 6 x 5
= 30 units²
