Answer:
12 units
Step-by-step explanation:
The area of a triangle can be found using:
a=(bh)/2
We know that the area is 24 units^2, and the height is 4. Therefore, we can substitute 24 in for a, and 4 in for h.
24=(b*4)/2
First, get rid of the denominator of 2. To do this, multiply both sides by 2.
2(24)=((b*4)/2)2
48=b*4
We are trying to find b, the missing side. To do this, we have to get b by itself. Since b and 4 are being multiplied, divide both sides by 4.
48/4=b*4/4
12=b
So, the missing side is 12 units
