Step-by-step explanation:
I don't exactly know what you are asking but here's what i thought when i saw this: The perimeter of a rectangle with a width of 13 units and a length of 14 units. The area of a square with side lengths of 9 units. The length of a rectangle with a width of 7 units and an area of 28 square units. The side length of a square with an area of 64 square units.
One of the rules of triangles is that if you have a 45 45 90 angle triangle, the two sides besides the hypotenuse are equal to each other. In this case, one of the sides is equal to x, so other side is equal to x as well. Now, to solve for x, you need to know the Pythagorean theorum:
Both 'a' and 'b' are equal to x, and 'c' is equal to 3, so I'll make the substitutions below:
This can be simplified to:
Now we just solve for x:
Solution:
