The perimeter of a rectangle is 30 inches if its length is three times it’s width find the dimensions

Length = 45/4 inches

Width= 15/4 inches

Step-by-step explanation:

Perimeter= 30 inches

Let width = x

Length = 3x

Perimeter = 2l + 2w

30= 2(3x) + 2(x)

30 = 2(3x+x)

30/2 = 3x+x

15 = 4x

x= 15/4

Hence width is 15/4

Then the length must be 3x = 3(15/4)

THEREFORE, Length = 45/4 inches

Width= 15/4 inches
