Answer:

x = -2

Step-by-step explanation:

The segments described in the question are equidistant (meaning they are the same length). Therefore, using algebraic techniques, we can set these two equal to each other and solve for x.

4x - 8 = 6x - 4 Combine like terms by subtracting 6x from both sides.

-2x - 8 = -4 Combine like terms by adding 8 to both sides.

-2x = 4 Divide by -2 on both sides of the equation.

x = -2

➷ Use this formula:

Area = ((a + b)/2) x h

a is the top length

b is the bottom length

h is the vertical height

1) Substitute in the values:

((3.8 + 6.2)/2) x 7 = 35ft^2 <== this is the answer

2) Substitute in the values:

((10.3 + 15.1)/2) x 12.6 = 160.02in^2 <== this is the answer
