It's too much trouble to look for it, Jessica, but I think we have done this problem for you in the last couple of days. Perhaps it was another student.
area triangle = area rectangle.
rectangle = 8" x 12" = 98 in2.
area triangle = 96 in2.
area triangle = 1/2*base*height.
96 in2 = 1/2*32*h
solve for h. I gret 6"
a rectangle and triangle have equal areas.the lenght of the rectangle is 12 inches, and its width is 8 inches.if the base of the triangle is 32 inches,what is the length in inches drawn to the base?
a)12
b)16
c)6
d)8
e)9

Area of the rectangle is length * width. Aread of the triangle is 1/2 base * height.
The length and width are given. Multiply them to find the area. Take that area to the triangle formula. Area = 1/2 base * height. The base is given. The only unknown is the height. That is solved by the equation. If you do the calculations you will get a number that is in the answer list.
