Question

The equation a=1/2(b1÷b2)h can be used to determine the area,a, of a trapezoid with height,h, and base lengths,b1 and b2 .Which are equivalent equations? Check all that apply.​

Answer 1

a.

d.

Explanation:

e2020 correct

Answer 2

`a=(1)/(2)b_1h+(1)/(2)b_2h`

Explanation:

We are given that an equation

`a=(1)/(2)(b1+b_2)h`

Base length of sides of trapezoid=
`b_1, b_2`

Height of trapezoid=h

It can be used to determine the area of trapezoid.

Because area of trapezoid=
`(1)/(2)(b_1+b_2)h`

We have to find the equation which is equivalent to given equation .

Expand the given equation

`a=(1)/(2)b_1h+(1)/(2)b_2h`

Hence, it is equivalent to given equation.

`a=(1)/(2)b_1h+(1)/(2)b_2h`
