The equation for area is lw=a lengthxwidth=area so you put in what you know. (area and width) and get 18L=450. divide both sides by 18 to make the L alone. 18L becomes L and 450 becomes 25. Length = 25 feet

You can find the area of the entire shape by finding the area of one of the split shapes individually

Formula for Square Area:
Length*Width
6*6=36
The area of the square is 36 in squared

Formula for Right Triangle Area:
Leg A*Leg B/2 (The lines which form the Right Angle)
6*6/2
36/2=18
The area of the right triangle is 18 in squared

Formula for the Equilateral Triangle Area: 
Base * Height/2
6*6/2
36/2=18
The area of the equilateral triangle is 18 in squared

Now add all the sums up
36+18+18
=72

The total area of the shape is 72 in squared

Hope this helps!

Owen is signing up for a gym membership with a one-time fee to join and then a
Katena32 [7]
The cost of the monthly fee is 50$.. if the joining fee is 100.. take 200 and subtract that fee since it is included in the total. You’re left with 100. Note, the 200 is calculated for a 2 month period, so split the remaining 100 ,from the total 200, into 2. You’re left with 50 each month.

T=(C-100)/2 (T being 1 month) (C being the total cost/200)

where
n is the total number of objects you choose from
r is the number that you choose to arrange

in this problem
n=4 </span>aluminum side panels measures

r=2 aluminum side panels measures

<span> C=4!/[(4-2)!*2!]-----> C=4!/[2!*2!]---> (4*3*2!)/(2!*2*1)
C</span>=6

1) 8 ft x 10 ft
