Answer:
<h2>LA = 24 ft²</h2>
Step-by-step explanation:
In the base we have the right triangle. Use the Pythagorean theorem for to calculate the hypotenuse:
The Lateral Area is the sum of the areas of three rectangles:
The Lateral Area:
I think it might be 43° because since the line is going through the middle, it would be 180-47-90=43 (the 90 came from the right angle)
hope this helps! :)
You first subtract 1/5 from both sides
3/4-1/5 = 11/20
3/2x=11/20
now you multiply 2/3 on both sides since you have to get x
11/20 * 2/3
x = 11/30
Area of a rectangle: 2(L+W)
length: 4+W
Area: 2(4+W) + 2W = 96
8+2W+2W = 96
8+4W = 96
4W = 88
W= 22cm
Calculate for length: 2L + 2(22) = 96
2L + 44 = 96
2L = 52
L = 26cm
• The length is 26cm and width is 22 cm.
1. The formula for calculate the perimeter of a rectangle, is:
P=2L+2W
P is the perimeter of the rectangle (P=320 feet).
L is the lenght of the rectangle.
W is the width of the rectangle.

2. The problem says that the length of the rectangle is three times the width, so you have:
</span>
L=3W
3. When you substitute L=3W and P=320, into P=2L+2W, you obtain:
P=2L+2W
320=2(3W)+2W
320=6W+2W
8W=320
W=320/8
W=40 feet
4. The barn forms one end of the rectangle. Therefore the linear feet of fence (x) is:
x=P-W
x=320 feet-40 feet
x=280 feet

How many linear feet of fence must he buy?

The answer is: 280 feet
