Question

find find the area of the shaded portion. all corners are right angled.​

Answer 1

Solution...

• first find small rectangle

Length = 12 - 4 m.

= 8 m.

breath = 18 - 1.5 + 1.5 m.

= 18 - 3 m.

= 15 m.

Area of Small rectangle = l × b

= 8 × 15 m.

= 120 m^2

• Now, Find large rectangle

Length = 12 m.

breath = 18 m.

Area of large rectangle = l × b

= 12 × 18 m.

= 216 m^2

Here..

Area of Shaded portion = Area of large rectangle - Area of small rectangle.

= 216 m - 120 m

= 96 m^2

Answer 2

Answer:

96sq.m

Step-by-step explanation:

Area of shaded portion=area of bigger square-area of smaller square

                                      =12x18  - 8x15

                                      =   216  -  120 =   96sq.m
