I have the problem:

A triangle has a base of 3.6 cm and an area of 22.32 cm squared. What is the height of this triangle. The teacher gave us the answer key and I know the answer is 12.4 but I don't know how they came to that answer. I can't figure out how you are supposed to solve it. Thanks...

To find the height of a triangle, you can use the formula for the area of a triangle:

Area = (base * height) / 2

In this case, you have the base and the area, so you can rearrange the formula to solve for the height:

height = (2 * Area) / base

Let's substitute the given values into the formula:

height = (2 * 22.32 cm²) / 3.6 cm

height = 44.64 cm² / 3.6 cm

height = 12.4 cm

Therefore, the height of the triangle is 12.4 cm.

To find the height of a triangle, you can use the formula for the area of a triangle:

Area = (1/2) * base * height

In this case, we are given the base (3.6 cm) and the area (22.32 cm²), and we need to find the height.

Let's start by rearranging the formula to solve for the height:

height = (2 * Area) / base

Now, substitute the given values into the formula:

height = (2 * 22.32 cm²) / 3.6 cm

Simplify:

height = 44.64 cm² / 3.6 cm

height ≈ 12.4 cm

So, the height of the triangle is approximately 12.4 cm.

Area of a triangle = 1/2 * base * height

Substitute what you know, then solve for what you don't know.

Area = 22.32
base = 3.6

Therefore:
22.32 = (0.5)(3.6)(h)
22.32 = (1.8)(h)
12.4 = h

I hope this helps.
