Question

Which equation can be used to calculate the area of the shaded triangle in the figure below? 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. 2(14 + 8) = 44 square feet 1 over 2.(14 + 8) = 11 square feet 2(14 × 8) = 224 square feet 1 over 2.(14 × 8) = 56 square feet

Answer 1

If it is a diagonal going from one corner to the other opposite corner about the center, the diagonal simple divides the area by 2.

So:

A=xy/2, and x=8 and y=14 in this case so:

A=(8*14)/2  or as you are probably looking at it (which is the same thing)

(1/2)(8*14)=56 square feet.

Answer 2

It is 56 square feet
