Question

find the area of the shaded portion in the following figures all measurments are given in cm​

Answer 1

Step-by-step explanation:

Area of rectangle = l × b

Area of first rectangle = 4 × 2

= 8cm,,

Area of second rectangle = 6 × 1

= 6cm,,

Area of third rectangle = 4 × 1

= 4cm,,

Area of square = S × S

= 1 × 1

= 1cm,,

So, area of shaded region = 8 + 6 + 4 + 1

= 19cm²,,

Here, l means length, b means breadth, S means side.
