Use the diagram to determine the base and the height of the triangle. the formula for the area of a triangle is a=bh/2

The answer is 32ft. What you have to do is multiply 10 and 6.4 which equals 64. Then you take 64 and divide it by 2 and you get the answer of 32. The equation goes like this 10ft X 6.4ft = 64ft/ 64ft divided by 2 = 32ft. 

So you all you do is muiltiply 6.4X10 which is 64 and then divide it by 2 which is 32
i hope this helps!!!

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
