Hey there! ☺☻☺

Perimeter of the given figure = Perimeter of rect. + Perimeter of square
= 2(l+b) + 4*side
= 2(15+10) + 4*15
= 2*25 + 60
= 50 + 60
= 110 cm

Hope It Helps You! ☺☻☺

Construction:
Construct an imaginary line between the red points in ur diagram.

Perimeter of the given shape = 3 sides of rectangle + 3 sides of a square + 5 m

We should calculate only 3 sides of a square and 3 sides of a rectangle as the fourth line is drawn imaginary.(see construction) and 5 m is included as the extra part of the fourth line gives up 1/3 of the whole side in square

Perimeter of the given shape = 2l+b + 3a + 5
= 2(15)+10 + 3(15) + 5
= 30 + 10 + 45 + 5
= 40 + 45 + 5
= 90 m

:) Hope this helps!!!
