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

1

A = bh

Suppose the base length of the triangle is 4 units shorter than the height. Rewrite A in terms of h only.

Respuesta :

Answer:

A is given by:

[tex]A = h^2 - 4h[/tex]

Step-by-step explanation:

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

This means that [tex]b = h - 4[/tex]

So

[tex]A = bh[/tex]

[tex]A = (h-4)h[/tex]

[tex]A = h^2 - 4h[/tex]

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