Given isosceles trapezoid trhy, in units what is the length of b2 if the height is 13 units, b1 is 21 units, and the area is 215 units squared?

We are given a trapezoid TRHY.

Height of the trapezoid = 13 units.

b1 = 21 units and

Area = 215 units squares.

We need to find the length of b2.

We know formula for area of a trapezoid.

Plugging values in formula.

215 = (21+b2)× 13.

215 = 6.5(21+b2)

Dividing both sides by 6.5, we get

33.08 = 21+b2.

Subtracting 21 from both sides, we get

33.08-21 = 21-21+b2

b2 = 12.08.

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
