Question

The formula for the area A of a triangle with base length b and height h is as follows.

Answer 1

Answer:

A is given by:

$A = h^2 - 4h$

Step-by-step explanation:

The base length of the triangle is 4 units shorter than the height.

This means that $b = h - 4$

So

$A = bh$

$A = (h-4)h$

$A = h^2 - 4h$

The expression for A in terms of h only was given above.
