Question

Write the area of the trapezoid in terms of a and b.

Answer 1

I am leaning towards answer a, but am not sure

Answer 2

a looks good to me.

Answer 3

so the two blue triangles are, (1/2)ab

the middle one is (1/2)c^2

c = sqrt(a^2 + b^2)

so the middle is

(1/2)(a^2 + b^2)

and the total is them added together

Answer 4

Thank you for confirming!
