Question

A rectangular room is 4 times as long as it is wide, and it’s perimeter is 60 meters. Find the dimension of the room

Answer 1

Answer: the length is 24m

The width is 6 m

Step-by-step explanation:

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

Perimeter = 2(L + W)

The perimeter of the given rectangle is 60 meters. This means that

2(L + W) = 60

Dividing through by 2, it becomes

L + W = 60 /2

L + W = 30 - - - - - - - - - - - - - -1

The rectangular room is 4 times as long as it is wide. This means that

L = 4W

Substituting L = 4W into equation 1, it becomes

4W + W = 30

5W = 30

W = 30/5

W = 6

L = 4 × 6

L = 24

Answer 2

Answer:

6,24

Step-by-step explanation:

Perimeter = 2(L+B)

60m is perimeter

L= length =4w

W= width

Perimeter = 2(l+b)= 2(4w+w) = 60

2(5w)= 60

10w = 60

W= 60/10=6

L= 4w=4×6=24
