Question

The triangle has an area of cm2 and a base of cm. What is the length of h?

Answer 1

$\boxed{h=7cm}$

Explanation:

The formula for finding the area of any triangle is given by:

$A=\frac{bh}{2} \\ \\ \\ Where: \\ \\ b:base \\ \\ h:height$

Let's assume a value for the area, we know that:

$b=5\frac{1}{4}cm=(5+\frac{1}{4})cm=\frac{21}{4}cm=5.25cm \\ \\ A=\frac{147}{8}cm^2=18.375cm^2 \\ \\ h=?$

Finding h:

$A=\frac{bh}{2} \\ \\ \\ Isolating \ h: \\ \\ h=\frac{2A}{b} \\ \\ h=\frac{2(18.375)}{5,25} \\ \\ h=7cm$
