Benjamin Ponce · Answer 1

Step-by-step explanation:

Perimeter = 2 x (length + width)

72 = 2 x (l + w)

Because l = w + 6

72 = 2 x (w + 6 + w)

= 2 x (2w + 6)

= 4w + 12

4w = 60

w = 15 cm

The answer is C.

Catalina Holland · Answer 2

let length of the rectangle be l

length is 6 cm longer than the width, w

l = w + 6

perimeter of rectangle is 72 cm

= 2l + 2w

substitute l = w + 6

2 (w+6) + 2w = 72

4w + 12 = 72

4w = 60

x = 15

ans is C. 15 cm
