The equation is 18.1 - x = -0.7

18.1 - -0.7 =
18.1 + 0.7 = 18.8

18.1 - 18.8 = -0.7

Step-by-step explanation:

we know that

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

$3,564=44*(2x-x)+\frac{1}{2}(2x-x)*44\\ \\3,564=44x+22x\\\\3,564= 66x\\ \\x=54\ ft$

The area of the triangle is equal to
