Braelyn is writing an equation to represent the perimeter of a rectangle with the width equal to half the length. She knows that

the perimeter is equal to 18 units and needs to find the length and width of the rectangle. Which equations represent this relationship? Check all that apply. x + one-half x = 18 2 x + x = 18 2 (x) + 2 (2 x) = 18 x + one-half x + x + one-half x = 18 2 (x + one-half x) = 18 2 x + one-half x = 18

Answer:

  • 2, 3, 4,5 are correct options

Step-by-step explanation:

  • <em>Perimeter of a rectangle equals to twice the sum of length and width:</em>
  • <em>P= 2(l+w)</em>

<u>Here we have:</u>

  • P = 18
  • w= l/2

<u>If we assume width = x, t</u>hen:

  • l = 2x
  • 2(x+2x) = 18 or
  • 2x + 4x = 18

<u>If we assume length = x, t</u>hen:

  • w = 1/2x
  • 2(x + 1/2x) = 18 or
  • 2x + x = 18

<u>Answer options:</u>

  1. x + one-half x = 18   === incorrect                        
  2. 2 x + x = 18               === correct
  3. 2 (x) + 2 (2 x) = 18     === correct
  4. x + one-half x + x + one-half x = 18 === correct, same as second option
  5. 2 (x + one-half x) = 18    === correct, same as second option
  6. 2 x + one-half x = 18     === incorrect

Answer:

base = 15 units

Step-by-step explanation:

We are given area of a triangle = 52.5 sq. units

Height is given as 7 and we have to find the base.

Using formula for area of triangle:

Area of triangle = \frac{base*height}{2}

52.5 = \frac{base*height}{2}

52.5 = \frac{base*7}{2}

52.5 * 2 = base × 7

105 = base × 7

base = 15
