this question about answer because i slove but this is very hard plzz give me answer​

Answer 1

Answer:Given figure are squares

In figure (a)

Perimeter of square=4xside

=4x80(m)

=320m

Now, perimeter of rectangular pieces cut out =2(l+b)

=2(20+15)(m)

=70m

Perimeter of remaining part

=320-70(m)

=250m

Similarly In figure (b)

Perimeter of square=240m

Perimeter of rectangular pieces cut out =70m

Perimeter of remaining part

=240-70(m)

=170m
