You need to lay communications cable around the perimeter of three offices, each 8' by 10'. How much cable do you need?

Respuesta :

Answer:

108 units

Step-by-step explanation:

We are given that

Length of each  office,l=10 units

Breadth of each office=b=8 units

Total number of office=3

We know that

Perimeter of rectangle=[tex]2(l+b)[/tex]

Using the formula

Length of cable for 1 office=[tex]2(10+8)=36units[/tex]

Length of cable required for 3 offices=[tex]36\times 3=108[/tex]units

Hence, the required length of cable=108 units
