What is the area of the white border

Answer 1

119 cm^2

Explanation:

To find the area of the white border, simply find the area of the outside rectangle and subtract the middle(dark) rectangle's area from that value.

White rectangle: 15x9 = 135

Dark rectangle: 8x2 = 16

135 - 16 = 119 cm^2
The unit is squared when finding the area of a two dimensional figure.
