Question

Find the area of the given figure only not perimeter​

Answer 1

Answer:

First find the area of the whole rectangle :

15 * 20

= 300.

Now find the area of the non-shaded region

5 * 5 to find one block

= 25

There are three blocks so

25 * 3

= 75

Now subtract the non-shaded region from the whole square.

300 - 75

= 225.
