What is the area of figure ABCD?

OpenStudy (anonymous):

OpenStudy (yoloshroom):

is it mulitple choice?

OpenStudy (anonymous):

yes

OpenStudy (yoloshroom):

can i get those choices? ^_^

OpenStudy (anonymous):

answers are: 84,98,105,112

OpenStudy (yoloshroom):

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?

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

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)

OpenStudy (anonymous):

35?

OpenStudy (yoloshroom):

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

OpenStudy (anonymous):

I did the math before the answer

OpenStudy (anonymous):

thank you

OpenStudy (anonymous):

closing now

OpenStudy (yoloshroom):
