Part 1)

Part 2)

Step-by-step explanation:

Part 1) we know that

The area of the figure is the area of one trapezoid multiplied by 2

Find the area of one trapezoid

we have

substitute

Find the area of the figure

Alternative Method

The area of the figure is equal to the area of a rectangle plus the area of triangle

so

Part 2) we know that

The area of the hexagon is equal to the area of one triangle multiplied by 6

Find the area of one triangle

we have

substitute

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
