Awall is 2m at one end and 2.4m at the other end. the area of the wall is 26.4m squared. what is the length of the wall?

Since the height is different on both ends, we can assume that the wall is a trapezoid. Knowing that, we can replace the measures we know in the formula and our onky variable is the length of the wall - we only need to isolate it. A= ((b+B)h)/2 26.4=((2+2.4)h)/2 52.8=4.4h h=12

A triangle that has an angle measuring exactly 90 degrees is a right triangle.
