Question

14. The length of a rectangle measures 15 centimeters. The perimeter of the rectangle is 48 centimeters. What does the width, w, of the rectangle measure? F. 16.5 cm, because 48-15 = W 2 :w 48-(2x15) G. 9 cm, because =W 2 H. 18 cm, because 48 - 2 x 15 = w J. 126 cm, because (48 + 15) x 2 = w

Answer 1

Perimeter of a rectangle:

`p=2(l+w)`

Given,

p=48cm

l=15cm

Substitute the known values in the formula,

`48=2(15+w)`
`48=30+2w`
`48-30=2w`
`2w=18`
`w=(18)/(2)`

Option G is the correct answer.
