The length of a postage stamp is
4 1/4
mm longer than its width. The perimeter of the stamp is
124 1/2
mm. Write an equation that represents the perimeter in terms of its width w. What is the width of the postage​ stamp? What is the length of the postage​ stamp?
Which equation represents the perimeter in terms of the width​ w?
A.
2w+(2w+124 1/2)=4 1/4
B.
2w+2(w+4 1/4)=124 1/2
C.
2w−2(w+4 1/4)=124 1/2
D.
w(w+4 1/4)=124 1/2

Respuesta :

Answer: Choice B

2W+2( W+4 1/4) = 124 1/2

=========================================

Explanation:

L = length

W = width

"The length is 4 1/4 longer than the width" (paraphrase) so

L = W + 4 1/4

This means,

P = perimeter = 124 1/2

P = 2L+2W

2L+2W = P

2W+2L = P

2W+2( L ) = P

2W+2( W+4 1/4) = 124 1/2
