# A rectangular sheet of paper is 12 (1/2) cm long and 10 (2/3) cm wide. Find its perimeter

**Solution:**

The perimeter of a rectangle can be calculated easily by adding lengths of four sides of the rectangle.

Length = 12 (1/2) cm = 25/2 cm

Breadth = 10 (2/3) cm = 32/3 cm

We know that,

Perimeter of the rectangle = 2 × (length + breadth)

= 2 × [(25/2) + (32/3)]

= 2 × {[(25 × 3) + (32 × 2)]/6}

= 2 × [(75 + 64)/6]

= 2 × [139/6]

= 139/3 cm

Therefore, perimeter of rectangular sheet of the paper is 46 (1/3) cm.
