A rectangle is shown with a width of 8 ft and a length of 14 ft. There is a diagonal line through the rectangle, and the bottom half is shaded in grey.

(4 points)

a
2(14 + 8) = 44 square feet
b
1 over 2. (14 + 8) = 11 square feet

c
2(14 × 8) = 224 square feet
d
1 over 2. (14 × 8) = 56 square feet

Answer 1

Explanation:

Area of triangle = 1/2 (base*height)

In this case, the base and height are equal to the two sides of the rectangle.

So, A = 1/2 (14*8) = 56 sq. ft
