Question

What is the length of the wooden strip required to frame a photograph of length and breadth 32 cm and 21 cm respectively?

Answer 1

The required length of the wooden strip to frame a photograph = Perimeter of the photograph.

Length of photograph = 32 cm.

Breadth of photograph = 21 cm.

Perimeter of photograph = 2 $\times$(length + breadth).

= 2 (32 + 21).

= 2 $\times$53 cm.

= 106 cm

Thus, the length of the wooden strip required is equal to 106 cm.
