1.How do you solve an area of a triangle by the base and height?
aleksandrvk [35]
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!
I HOPE THIS HELPED YOU!!!!
