The formula for the area of a triangle is A = -bh, in which b represents the
length of the base and h represents the height. If a triangle has an area of 140
mm2 and the height is 14 mm, what is the measure of the base?

20mm

Step-by-step explanation:

The problem gives A=140mm^2 and h=14mm

It also gives the equation A=1/2bh

Plug in what you know --> 140=1/2(b)(14)

To solve for b, fist multiply 140 by 2

Now we have 280=14b

Divide by 14, and you get your answer of b=20mm

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
