Xy = 22
1 1

Cross multiply:
xy * 1 = 1 * 22

Simplifying
xy * 1 = 1 * 22

Reorder the terms for easier multiplication:
1xy = 1 * 22

Multiply 1 * 22
1xy = 22

Solving
1xy = 22

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '1y'.
x = 22y-1

Simplifying
x = 22y-1

What is the area of this trapezoid? Enter your answer in the box.

olga2289 [7]

The formula for area of a trapezoid is
$\frac{(b1 + b2) \times h}{2}$
so you add up the bottom base (17) and the top base (3) to get 20.
you then take the sum of the bases (20) times the height (8) to get 160.
lastly, you take 160 ÷ 2 to get your final answer, which is 80 (:
