the poster has a border whose width is 2 cm on each side. if the printed material has the length of 6 cm and width of 8 cm, then find the area of the border.

Respuesta :

Since the border has a width of 2cm, the length of the printed material and its border

is 2 + 6 + 2 = 10cm

and it's width iis

2 + 8 + 2 = 12cm

Hence the area is 10 x 12

Therefore,

the area of the border = 10x12 - 6x8 = 120 - 48 =72 square centimeters
