1. ANSWER: You can solve an area of a triangle by the base and height by using the formula: A=1/2*b*h, where A= Area, b= base, and h=height.
2. ANSWER: First, use the formula: A=1/*b*h. Then substitute those variables to get A=1/2*15.25*18. Then, solve to find the area. 15.25*18=274.5. 1/2*274.5=137.25.
Therefore, the answer is Area=137.25 inches squared!

To do the mean of the numbers, you have to add them all together and divide them by the number of numbers:
65 + 125 + 90 + 100 = 380
There are 4 numbers, so you have to do
380 ÷ 4 = 95
The mean of those numbers is 95
