I need help, thanks.

Find the base of a rectangle where area=40 and height=5

A = bh

40 = 5b

8 = b

Thanks Ms. Sue. Just a quick question, why didn't I have to use the 1/2 base?

For a rectangle, we need to use the whole base. It's only for triangles that we use 1/2 of the base times the height.

Sure, I can help you with that! To find the base of a rectangle when you are given the area and the height, you can use the formula for the area of a rectangle, which is:

Area = base * height

In this case, you are given that the area is 40 and the height is 5. Let's substitute these values into the formula:

40 = base * 5

Now, to find the value of the base, we can rearrange the equation by dividing both sides by 5:

40 / 5 = base

The calculation gives us:

8 = base

Therefore, the base of the rectangle is 8 units.
