area = 2,142

perimeter = 70

Step-by-step explanation:

area = length x width x height

a=18 x 17 x 7

perimeter = all sides added together and assuming it is a rectangle...

p=18 + 18 + 17 + 17

<u>Trigonometry</u>

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Identify</u>

<em>a</em> = 12

<em>b</em> = 5

<em>c</em> = x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [PT]:                                                                           12² + 5² = x²
  2. Evaluate exponents:                                                                                      144 + 25 = x²
  3. Add:                                                                                                                 169 = x²
  4. [Equality] Square root both sides:                                                                 ±13 = x
  5. Rewrite:                                                                                                           x = ±13

Since we are dealing with positive numbers, we can disregard the negative root.

∴ x = 13
