A school is painting its logo in the shape of a triangle in the middle of its sports field. The school wants the height of the t

Radda [10]

Answer:

$b\geq 9$

In other words, the base must be at least 9 feet long.

Step-by-step explanation:

The schools wants the height of the triangle to be eight feet, and the area of the logo to be at least 36 square feet.

Recall that the area of a triangle is given by:

$\displaystyle A = \frac{1}{2}bh$

Since we want to area to be at least 36 square feet:

$\displaystyle \frac{1}{2}bh \geq 36$

We are given that the height is eight feet. Substitute:

$\displaystyle \frac{1}{2}(8)b\geq 36$

Simplify:

$4b\geq 36$

Divide both sides by four. Hence, our inequality is:

$b\geq 9$

In words, this means that the base must be at least 9 feet long.
