Question

What is the length of a coloured tape required to stick on the side of a rectangular scenery. The length of the scenery is 20 cm and the breadth is 12 cm .

Answer 1

Hint: Perimeter is the continuous line forming the boundary of a closed geometric figure. The given dimensions of the scenery are length - 20cm and breadth – 12 cm. We have to find the perimeter of the scenery to get the required length of the coloured tape.

Complete step-by-step answer:

The length of the scenery is 20 cm and the breadth is 12 cm .
The perimeter of rectangular scenery is $2(l + b)$
So, keeping vale in the given formula,
Perimeter = $2(20 + 12)$
first solve the term inside the bracket. So, we
  = $2 \times 32$
 = $64cm$
Therefore the required length of the coloured tape is 64cm.
So, the correct answer is “64cm”.

Note: A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex meet at right angles. The opposite sides of the rectangle are equal in length which makes it different from a square. The rectangle is a symmetrical shape and has both the diagonals equal in length.
