A rectangular carpet measuring 16 m by 12 m (excluding the border) has a border of width 2m on each of its sides. What is the area of the border Correct Answer 128m2

Measurements of the carpet with borders are (16 + 2x2) or 20 m and (12 + 2x2) or 16 m. Area of the carpet with borders = 20 x 16 = 320 m2 Area of the carpet without borders = 16 x 12 = 192 m2 So, area of the borders = 320 - 192 = 128 m2
