Question

The construction blueprints display the plans to build for the student parking lot. The outline represents the proposed shape of the parking lot. Find the perimeter of the proposed parking lot.

Answer 1

8x-10

Explanation:

x+(x-5)+((2x+15)-x)+((2x-5)-(x-5))+(2x+15)+(2x-5)

x+x-5+2x-15 -x+2x-5-x+5 +2x+15+2x-5

4x-20 +0 +4x+10

8x-10

Answer 2

8x + 20

Explanation:

As we know that perimeter is the sum of all sides. So,

Let's find all the sides first.

• 2x - 5
• 2x + 15
• x
• 2x + 15 - x = x + 15
• x - 5
• 2x - 5 - (x - 5) = 2x - 5 - x + 5 = x

Now, we can find the Perimeter.

Perimeter = Sum of all sides

= 2x - 5 + 2x + 15 + x + x + 15 + x - 5 + x

Simplify like terms

= 2x + 2x + x + x + x + x - 5 + 15 + 15 - 5

= 8x + 20

Therefore, the perimeter of the proposed parking lot is 8x + 20.
