Jazmine Bauer · Answer 1

The formula for the area of a triangle is Area=.5 (b) (h)

So fill in what you know:

120=.5b*15

Then solve for b.

120=7.5b

b=16

Paris · Answer 2

area for triangle = 1/2 x b x h

area = 120

height = 15

120 = 1/2 * b * 15

divide both side by 1/2

240 = b * 15

divide both sides by 15

b = 240/15 = 16

base is 16 inches

check: 1/2 * 16 * 15 = 120 sq. in.
