Answer 1

Heyy Buddy ❤

Here's your Answer...


Given,

Length = 40cm..

Breadth = 36 cm.

For the new Rectangle,

Length = (40 - 3.5 - 3.5)cm. = 33cm

Breadth = (36 - 3.5 - 3.5) cm = 29cm

So,

Perimeter of new Rectangle = 2 ( l + b)

=> 2( 33 + 29)

=> 2 × 62

=> 124cm.

Answer 2

l= 40 b =36

and wide = 3.5 cm

so new l = 40-3.5-3.5 = 33cm

b = 36-3.5-3.5= 29 cm

so perimeter = 2(33+29)

= 2×62
=124 cm
