Answer:
11 - 35
12 - 32
13 - six and two thirds
14 - 12.5
Step-by-step explanation:
The first problem can be solved using Pythagorean theorem. If we set variables a, and b for the legs, and c for the hypotenuse. a^2+b^2=c^2. Solving for c in this equation we can find that the length of the slide is 35
In the second problem we can see the middle shape is rectangle so the side paralell to the side on the top is also equal to seven. We can find the missing side on the triangles through Pythagorean theorem. We can find that the missing side is four. Adding up all the sides we can find the perimeter is 32.
We can also solve the third and fourth problems using Pythagorean theorem. The answer for the third is approximately 6 and two thirds. The answer for the fourth is 12.5
