Answer:
40cm
Step-by-step explanation:
1. To find the missing leg, use the Pythagorean theorem a²+ b² = c² and substitute the numbers a² + 8² = 17².
2. So a = 15 since 17²-8² = 289 - 64 =225 and the square root of 225 is 15
3. Now that all the lengths have been found. So the perimeter of the right triangle is 40cm.

When you cut a square horizontally or vertically, you get two smaller triangles that are half the area of the square. When you split the rectangle again, you get a square 1/4 the size of the regular square.
Let's say the question is 2(x+3),
You multiply the number outside the brackets by EVERYTHING inside the brackets so,
2(x+3)
=2x+6 *Notice how 2(x)=2x and 2(3)=6.*
Yes , Rational numbers are fractions
