A rectangle is 7 times as long as it is wide. The perimeter is
64 feet. Find the dimensions. The length is ???feet where the width is ???feet.

Please show a step by step on how to do this.

Length = 28 feet

Width = 4 feet

Step-by-step explanation:

Let L represent the length of the rectangle.

Let W represent the width of the rectangle.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of the rectangle is 64 feet. This means that

2(L + W) = 64

Dividing through by 2, it becomes

L + W = 32 - - - - - - - - - - - -1

The rectangle is 7 times as long as it is wide. This means that

L = 7W

Substituting L = 7W into equation 1, it becomes

7W + W = 32

8W = 32

W = 32/8

W = 4

L = 7W = 7 × 4

L = 28

x=half

step-by-step explanation:

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
