उत्तर

Area of shaded portion in the following figure is 10 cm2.

Explanation:


From the figure, length of rectangle = 5 cm and,

breadth of the rectangle = 3 cm + 1 cm = 4 cm

So, area of rectangle = length × breadth

= 5 × 4

= 20 cm2

By observing the figure, the shaded part covered exactly half of the rectangle,

Therefore, area of shaded part is = `"Area of rectangle"/2` 

= `20/2`

= 10 cm2
