The area of a rectangular gymnasium is (5x+5x) square feet. If it is 5x feet wide, what is the length, in feet?
Amiraneli [1.4K]

Answer:

Step-by-step explanation:

Area = L x W      gym area is (5x + 5x) ft²      if   W = 5x      Find the L

Area = L x W       divide both sides by W

Area/W  = (L x W) / W

Area/W  =  L  =  Area/W

    L = Area/W

       =  (5x + 5x) / (5x)

       =  5x( 1 + 1) / 5x

       =  5x(2) / 5x                      the 5x's cancel each other  5x/5x = 1

       =   2 ft          I got 2.  I suspect the 12 was a typo and should have been 2

PLEEEAAAAAASE HELP!<br>What is the answer to this question?<br><br>​
IrinaVladis [17]

Answer:

  • 23 units

Step-by-step explanation:

<em>Perimeter is the sum of side lengths</em>

<u>Let's find the sides first</u>

  • AB = √(-2- 2)² + (-4+1)² = 5
  • BC = (2 - (-1)) = 3
  • CD = √(-1- 2)²+(5-2)² = √18 = 3√2 = 4.24
  • DE = √(-4 -(-1))²+(2-5)²= √18 = 3√2 = 4.24
  • AE = √(-4-(-2)²+(2-(-4))²=√40= 2√10 = 6.32

<u>Perimeter is</u>

  • P = 5 + 3 + 4.24 + 4.24 + 6.32 = 22.8 ≈ 23 rounded to the nearest whole number
