The following is the formula for finding the area (A) of a trapezoid with height (h) and bases (b1) and (b2). A = 1/2h(b1 + b2)

charle [14.2K]

Answer:

<em>Correct choice: B</em>

Step-by-step explanation:

<u>Equation Solving</u>

The area of a trapezoid with height h and bases b1 and b2 is given by:

$\displaystyle A=\frac{1}{2}h(b_1+b_2)$

We must solve this formula for h.

First, multiply by 2 to eliminate denominators:

$\displaystyle 2A=h(b_1+b_2)$

Now, divide by b1+b2:

$\displaystyle \frac{2A}{b_1+b_2}=h$

Swapping sides:

$\displaystyle h=\frac{2A}{b_1+b_2}$

Correct choice: B

Solve for x than find the perimeter

My name is Ann [436]

Answer:

136 in

Step-by-step explanation:

Assuming the figure is a square with equal sides, then

4x - 2 = 3x + 7 ( subtract 3x from both sides )

x - 2 = 7 ( add 2 to both sides )

x = 9

Thus side = 3x + 7 = 3(9) + 7 = 27 + 7 = 34

Thus

perimeter = 4 × 34 = 136 in
