## JessAmazzing 3 years ago Write the area of the trapezoid in terms of a and b.

Okay do you know that the area of a trapezoid = (1/2)*(sum of parallel sides)*height. ??

3. lgbasallote

this isnt any ordinary trapezoid...

4. lgbasallote

the area of this is the sum of the area of the three triangles

5. apoorvk

yeah, but i don't even need to find the area of the three triangles, though lgba, you are right too. The length of the two parallel sides = a and b each. height of the trapezoid (or distance between the parallel sides) = a + b Can you work this out now, @JessAmazzing

6. lgbasallote

it seems so

7. JessAmazzing

I'm confuseddddd. lol

8. apoorvk

no worries. what's the length of each parallel side? And so what would be their sum??

9. apoorvk

C'mon, calm down and try to think - this is a stupid problem, you'll be able to get this in a jiffy. @JessAmazzing

|dw:1338400172456:dw| area of P is ab/2 of Q is c^2/2 of R is ab/2 as P and R are triangles, also Q but it is half of the square of side c
