Answer:

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:

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

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

Simplify:

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

In words, this means that the base must be at least 9 feet long.
It is 5 because any thing times 1 is that number
I don’t really understand what this is asking but the formula for circumference is C= πd Remember that diameter (width of the circle) is double the radius (half the width of the circle) and π is about 3.14
Hope this helped
