At a community center, you want to rope off an area that is adjacent to a building. The length of the building is 10 ft. You have 42 ft of rope. What are the possible widths of the roped-off area?

Respuesta :

Answer: The width of the roped off area would be 11 feet.

Step-by-step explanation:

Since we have given that

Length of rope = 42 feet

Length of building = 10 feet

Since you want to rope off an area that is adjacent to a building.

So, As we know that Perimeter of rectangle is given by

[tex]Perimeter=2(l+b)\\\\42=2(10+b)\\\\\dfrac{42}{2}=10+b\\\\21=10+b\\\\21-10=b\\\\11=b[/tex]

Hence, the width of the roped off area would be 11 feet.
