The back frame of a dog house is in the shape of a triangle with an area of 6 square feet. the height of the frame is 4 feet.what is the width of the frame?

The formula for finding the area of a triangle is A = 1/2 b x h

Since we are given the area and the height, we can easily substitute these values into the equation then solve for the unknown width (base).

A = 1/2 b x h
6 = 1/2 b x 4
12 = b x 4
12/4 = b
b = 3 ft

Check the answer by plugging back into the formula
6 = 1/2 (3 x 4)
6 = 1/2 * 12
6 = 6  True statement so it checks!

I think the answer is A.
