Question

.. Find the area of the shaded parts. 15 m (i) | () 1 4 m 10 m 1. 6 m +​

Answer 1

Answer:

126m²

Step-by-step explanation:

In the given figure, there are two rectangles.

We are asked to find out the area of the shaded part of the outer rectangle.

First, we need to find the total area of the outer rectangle.

$area \: of \: the \: rectangle = l \times b \\ \: \: \: \: \: \: \: \: \: \: = 15m \times 10m \\ = 150 {m}^{2}$

After finding the area of the outer rectangle, we are required to find the area of the inner rectangle.

$area = 4m \times 6m \\ \: \: \: = 24 {m}^{2}$

Now, we need to subtract the area of the inner rectangle from the area of the outer rectangle.

$150 {m}^{2} - 24 {m}^{2} = 126 {m}^{2}$

Therefore, the area of the shaded part is 126m²

Answer 2

Answer:

shaded region=area of big rectangle-area of small rectangle

Step-by-step explanation:

1. area of big rectangle=l×b

15×10=150

so the area of big rectangle is 150cm2

area of small rectangle=l×b

4×6=24cm2

therefore

150-24=126cm2

hence the area of shaded region is 126cm2
