Treat the face of the triangle as the base and use the formula $(2*base)+(perimeter*height)$ The perimeter is the perimeter of the base and the height would be the length of the rectangle.

idk which one is which @LegendarySadist

No need to tag me, I'm right here. And when you say you don't know which one is which, what are you referring to?

5. anonymous

like in the equation you said what am i plugging in where?

6. anonymous

The base is the area of the triangle, the perimeter is the perimeter of the triangle, and the height is the length of the rectangle.

7. anonymous

ohh ok but how do i find them, like the equations

8. anonymous

Equations?

9. anonymous

yea the area and perimeter

10. anonymous

Area of a triangle: $\frac{ height*base }{ 2 }$ Use the Pythagorean theorem to find the other leg, and then add the legs for the perimeter.

I'm so confused..

12. anonymous

Why are you doing surface area problems if you don't know how to do area or perimeter? Those should come first in any course.

idk lol it so confusing
