Answer» Answer: AREA of BORDER = 64m² Step-by-step explanation: Length of inner rectangle = 20m Breadth of inner rectangle = 10M Area of inner rectangle = lb = 20m × 10m = 200m² Length of outer rectangle = 20 + 2 = 22m Breadth of outer rectangle = 10 + 2 = 12m Area of outer rectangle = lb = 22m × 12m = 264m² Area of border = Area of outer rectangle - Area of inner rectangle Area of border = 264m² - 200m² = 64m².

Find the area of the border (shaded portion) from the following figures

Answer»

Answer:

AREA of BORDER = 64m²

Step-by-step explanation:

Length of inner rectangle = 20m

Breadth of inner rectangle = 10M

Area of inner rectangle = lb = 20m × 10m = 200m²

Length of outer rectangle = 20 + 2 = 22m

Breadth of outer rectangle = 10 + 2 = 12m

Area of outer rectangle = lb = 22m × 12m = 264m²

Area of border = Area of outer rectangle - Area of inner rectangle

Area of border = 264m² - 200m² = 64m².
