k, so first we want to find the area of the triangle, then add that to the area of the rectangle.
How would u begin finding the area of the triangle?
OpenStudy (anonymous):
multiplication?
OpenStudy (anonymous):
is the triangle 4 inches?
OpenStudy (yoloshroom):
area of the triangle is 1/2bh right?
So we'd solve for that, the Height is 7 inches, and the base of the triangle is 4 inches right?

is it 7 x 4
OpenStudy (yoloshroom):
(7x4)/2
OpenStudy (anonymous):
28 divided by 2?
OpenStudy (yoloshroom):
yup, so the area of the tirangle is 14.
so area of ADE = 14
then we'd do 14+(AB)(BC)
so it'd be... 14+(14)(7)

no no, 14+14x7 ^_^
OpenStudy (anonymous):
7*14 + 1/2 * 7*4
OpenStudy (anonymous):
total area is the area of the rectangle plus the area of the triangle.
OpenStudy (anonymous):
196?
OpenStudy (anonymous):
7*14+1/2*7*4 = 112
