Question

The width of a rectangle measures (4d – 8) centimeters, and its length measures

(7d – 3) centimeters. Which expression represents the perimeter, in centimeters, of
the rectangle?

Answer 1

(22d-22)cm

Explanation:

Perimeter = 2 x (width + Length)

= 2 x [(4d – 8) + (7d – 3)]

= 2 x (11d-11)

= (22d-22)cm

Answer 2

(22d-22) cm

Explanation:

perimeter= 2×(4d-8+7d-3)

= 2× (11d-11)

(22d - 22) cm
