What is the base of the triangle?

Question

The height of a triangle is 7 cm longer than its base.

The area of the triangle is 60 cm².

What is the base of the triangle?

Answer 1

Using the formula Area = (1/2)base*height, you can find the answer.

You will usually see this formula written as A = (1/2)*b*h.

To solve for b, you can rewrite the formula as b = 2A/h.

Plug in 60 for area and 7 for height, and then solve for base.

After plugging your numbers in, it will look like b = 2*60/7

Simplify and your answer is b = 17.142 (rounded to 3 decimal places)
