Question

coach silva is designing a rectangular practice field for a soccer game. the length of the practice field is 4 yards longer than its width. write an expression to represent the area of the practice field in terms of the width, w, of the practice field. a $4w + 8$ b $w^2 + 4$ c $w^2 + 16$ d $w^2 + 4w$

Explanation:

Step1: Define length in terms of w

Length $l = w + 4$

Step2: Apply rectangle area formula

Area $A = l \times w = (w + 4)w$

Step3: Expand the expression

$A = w^2 + 4w$

Answer:

D. $w^2 + 4w$
