Question

Find the area of the shaded portion. All corners are right angled
​

Answer 1

Answer:

96m²

Step-by-step explanation:

Area of the shaded portion = Area of the outer rectangle ABCD - Area of inner rectangle EFGH

Length of the outer rectangle ABCD = 12m.

Breadth of the outer rectangle ABCD = 18m.

Area of the outer rectangle ABCD = Length × Breadth

= 12m × 18m

= 216m²

Length of the inner rectangle EFGH = ( 12m-4m )

= 8 m

Breadth of the inner rectangle EFGH = ( 18m - 1.5m + 1.5m )

= ( 18 m - 3m )

= 15m

Area of the inner rectangle EFGH = Length × Breadth

= 8m × 15m

= 120m²

Area of the shaded portion = Area of the outer rectangle ABCD - Area of inner rectangle EFGH

Area of the shaded portion = 216m² - 120m²

Area of the shaded portion = 216m² - 120m² = 96m²
