3.5*5.5=19.25
The formula to find the area is the length times width
You need to use Pythagoras’ Theorem.
A² + B² = c² and c is the hypotenuse of the right angled triangle.
The height of the tower (5 feet) is A and the distance from the end of the cable and the base of the tower (12 feet) is B. The length of ONE cable is c. So:
A² + B² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
13 = c. This is the length of one cable.
3 x 13 = 39 therefore the total length of the cables is 39 feet.

The simplest form can be 13/3: 7 or 4.3:7
Answer:27
Step-by-step explanation:
A=((b1+b2)/2)h
A=((12+6)/2)(3)
A=((18)/2)3
A=27
