Answer:
240
Step-by-step explanation:
Assign Variables:
(I will choose mine a little bit differently)
d = length of garden
d = 20 feet
w = width of garden
A = area of garden
Equations and Solution:
A=d%2Aw and perimeter given as 64 feet means 2d%2B2w=64.
We know what is the d value, so we want to solve for w.
-
2w=64-2d
w=32-d
w=32-20
highlight%28w=12%29 feet
-
FINDING AREA VALUE
A=d%2Aw
A=20%2A12
highlight%28A=240%29 square feet
Answer:
none of the above
Step-by-step explanation:
A= (1/2) b*h
h=3 sqrt3
A= (1/2)*6*3sqrt3
A= 9sqrt3 square inches
