Answer:
47.856
Step-by-step explanation:
We will use
SOH
CAH
TOA
to solve this
we have the adjacent length, but need the hypotonouse
which means that we will use CAH
we have
cos(43)= 35/p
solve for p
47.856
The area of the parallelogram is the product of its base length and height, (12 ft)*(12 ft) = 144 ft^2.
The area of the cutout is the product of its base length and height, (6 ft)*(8 ft) = 48 ft^2.
The shaded area is the area of the parallelogram less the area of the cutout,
144 ft^2 -48 ft^2 = 96 ft^2.
L=w+9
p=2w+2l
p=2w+2*(w+9)
p=2w+2w+2*9
p=4w+18
4w+18=38
4w=38-18
4w=20
w=20:4
w=5 in
l=5+9=14 in
Step-by-step explanation:

where n starts from 0.
so the answer is :
16+5=21,
25+7= 32
