Answer:
The length of 2 wires are 13 feet and 12 feet [i don't know if the 3rd side is a wire, if so, the length is 5 feet]
Step-by-step explanation:
<em>The image of the tent is attached.</em>

As we can see, it creates a right triangle with "x+8" side being the hypotenuse of the triangle.
The pythagorean theorem tells us:
Hypotenuse^2 = Leg^2 + Leg^2
THe hypotenuse is "x+8", the two legs are "x" and "x+7" respectively. Let's solve for x:
We expand and solve for x:
Length can't be negative, so x = 5.
Hence, the 3 sides of the triangle are:
x = 5
x + 8 = 13
x + 7 = 12
The length of 2 wires are 13 feet and 12 feet

Answer: 225 square feet
Step-by-step explanation:
We find the area of the 4 triangle and the area of the rectangle and thereafter we add everything together.
Area of triangle 1 = 1/2 base × height
= 1/2 × 12 × 8
=96/2
=48
Area of triangle 2 = area of triangle 1= 48( because the opposite triangle are congruent so they have equal base and height)
Area of triangle 3 = 1/2×base×height
= 1/2 × 6 ×9.5
= 57/2
=28.5
Area of triangle 4=Area of triangle 3 = 57 (the opposite triangle are congruent and so they have the same base and height hence the same area)
Area of the rectangle = length×breadth
=12 × 6 =72
Total surface area = addition of all the areas of the triangles and the rectangle
Total surface area= 48+48+57+57+72 = 225
Therefore, the total surface area is 225 square feet
