Question

A triangle has an area of 125 sq cm. If its base is 25 cm, what is height?

Answer 1

Area of the triangle is 125 sq cm.
Base of the triangle is 25 cm.
Area of a triangle = $\frac{1}{2}$ × Height × Base
125 sq cm = $\frac{1}{2}$ × Height × 25
$\mathrm{Height}=\frac{250\mathrm{sq}\mathrm{cm}}{25\mathrm{cm}}$
∴ Height = 10 cm
∴ The height of the triangle is 10 cm.
