Left triangle area
.. (1/2)*(30 ft)*(72 ft) = 1080 ft^2
Middle walkway area
.. (20 ft)*(72 ft) = 1440 ft^2
Right triangle area
.. same as left triangle area, 1080 ft^2
Total area
.. 1080 ft^2 +1440 ft^2 +1080 ft^2 = 3600 ft^2
_____
Check:
Parallelogram area = base*height = (50 ft)*(72 ft) = 3600 ft^2
To find the value of x, assuming it is the value of the missing angle in the quadrilateral, you need to know that the sum of the angles in any quadrilateral equals 360.
360 - (66 + 95 + 114) = 85 degrees.
x = 85 degrees
Factor the numerator to get:
(-3z(z+5))/(z+5) now you notice that (x+5) cancel out leaving:
-3z
