last question!

OpenStudy (anonymous):

65*15 + 25*15= 15*90=1350

OpenStudy (anonymous):

got it or not?

OpenStudy (anonymous):

I got 1190

OpenStudy (anonymous):

sides of trapezoid are 45 and 20, height 15 base of triangle 25, height 15 now, apply formula, didnt multiply with 1/2 because there r 2 trapezoids and 2 triangles

OpenStudy (anonymous):

I tried it again and got 862.5

Directrix (directrix):

I got 1350 square feet. Let me type up my work so it can be checked.

OpenStudy (anonymous):

Good idea.

Directrix (directrix):

Two congruent isosceles triangles and 2 congruent isosceles trapezoids. 2 (1/2)[ (25) (15)] + 2 (1/2) [ (15) (20 + 45)] = 25* 15 + 15*65 = 1350 square feet

OpenStudy (anonymous):

I get 2325

OpenStudy (anonymous):

Oh nevermind! I got it

Directrix (directrix):

Here is the part for the two triangles: 2 (1/2)[ (25) (15)] --> Did you get 375? Here is the part for the two isosceles triangles: 2 (1/2) [ (15) (20 + 45)] -->975

OpenStudy (anonymous):

Thank you, and good night!

Directrix (directrix):

Okay, same to you. I'll look over your other work so that I'll be up to speed or whatever.

OpenStudy (anonymous):
