Question

A rectangular wooden piece having length 40 cm and breadth 30 cm, then find its perimeter.Find perimeter of it.

Answer 1

Given...

A rectangular wooden piece having length 40 cm and breadth 30 cm

So.. Length = L = 40cm

Breadth = B = 30 cm..

We know that...

Perimeter of a rectangle = 2(L + B)

= 2(40cm + 30cm)

=2(70cm)

=140cm..

so the length of rectangle= 40cm..

Breadth= 30cm ...The Perimeter of it = 140cm

Answer 2

Solution :

Dimensions of a rectangular wooden

piece :

length ( l ) = 40 cm

breadth ( b ) = 30 cm

Perimeter ( P ) = 2( l + b )

= 2( 40cm + 30cm )

= 2 × 70 cm

= 140 cm

Therefore ,

Perimeter of the rectangular wooden

piece = 140 cm
