Question

Is 73.5 the answer? Didn’t get clarification from last tutor.

Answer 1

The are of the triangle is given as follows:

$\text{Area}=\frac{1}{2}\times base\times perpendicular\text{ height}$

From the triangle given, we have:

base = 21cm

perpendicular height = 7cm

Thus:

$\text{Area = }\frac{1}{2}\times21\times7=\frac{147}{2}=73.5\text{ square centimeters}$
