The shape is a triangle.
the area is 12 centimeters
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
Step-by-step explanation:
4 x 3 + 6
12 + 6
= 18
or
4 x (3+6)
4 x 9
= 36
depends whether the 3+6 is in brackets :)
Answer:
80
