Answer 1

We can divide the above figure into two rectangles MNSR and OPQS.

The dimension of rectangle MNSR is 3 x 4 (Since, MR = 3 and MN = 4).

So, area of rectangle MNSR = 3* 4 = 12 square units.

Similarly dimension of rectangle OPQS is 3 x 1 because

PQ = MR - NO = 3 - 2 = 1

SQ = RQ - MN = 7 - 4 = 3.

So, area of OPQS = 3* 1 = 3 square units.

Hence, the area of polygon MNOPQR = Area of rectangle MNSR that is 12 square units + Area of rectangle OPQS that is 3 square units.

= 12 + 3

= 15 square units.

Hope this helps you!
