A triangle has an area of 48 square feet. The height is 12 feet. What is the length of the base (in feet)?

Answer 1

This is finding the area of a triangle

Area= 48 square feet

Height =12 feet

Base=X

Remember the formula of finding area of triangle is this:

1/2 bX h= area

In this case the area is given and the height is given we need to find the base.

We plug in the values in the formula

48=1n/2 X12

48x2=(1n/2)X2X12

You multiply each side by 2. The 2 eliminates from the second half of the equation.

96=1nx12

96=12n

Next after you multiplied the second half by 12 you have to divide the equation.

96=12n

__ __

12 12

n=8

The solution is n=8

Next you have to divide this answer into half.

So the answer to this problem is 4.

Answer 2

Area = 1/2 b h

So b = 2 x Area / height

You can now find the base
