Question

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

Answer 1

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=$2(l+b)$

Using the formula

Length of cable for 1 office=$2(10+8)=36units$

Length of cable required for 3 offices=$36\times 3=108$units

Hence, the required length of cable=108 units
