Question

What is the perimeter, in square centimeters, of a rectangle that has a length of 4 centimeters and a width of 15 millimeters? 38 cm 19 cm 5.5 cm 11 cm

Answer 1

11

Explanation:

15 millimeters is 1.5 cm

1.5 + 1.5 + 4 + 4 = 11 cm

Answer 2

11 cm

Explanation:

The rectangle width is 15 mm, which is the same as 1.5 cm.

The formula for P is P = 2W + 2L.

Here, with W = 1.5 cm and L = 4 cm, P = 2(1.5 cm) + 2(4 cm) = 11 cm
