Answer 1

The expression which represents the perimeter, in centimeters, of the rectangle is; (18d +10f) centimetres.

Perimeter of a rectangle

Since the perimeter of a rectangle is given by the formula;

• Perimeter, P = 2l + 2w.

In essence, Perimeter, P = 2(2d – 3f) + 2(7d + 8f)

• P = 4d -6f + 14d +16f

• P = 18d +10f.

Ultimately, the perimeter of the rectangle is; (18d +10f) centimetres.
