Given:

For rectangle,

Length = l = 12.5 m

Breadth = b = 5.5 cm

To find:

Perimeter of rectangle = ?

Solution:

Here we have to convert centimeter into meter or according to our need, we can convert meter to centimeter

100 cm = 1m

$\\ \\ 1 \: cm \: = \dfrac{1}{100} \: m \\ \\ 5.5 \: cm \: = 5.5 \times \dfrac{1}{100} \: m \\ \\ = 5.5 \times 10 {}^{ - 2} \: m \\ \\ = 0.055 \: m$

Breadth = b = 5.5 × 10^-2 = 0.55 m

Perimeter of rectangle = 2 ( length + breadth)

Perimeter = 2 ( 12.5 + 0.055)

Perimeter = 2 × 12.555 m

Perimeter = 25.11 m

Answer:

Thus, Perimeter of rectangle is 25.11 m

Knowledge booster:

• Always solve by making the units like meter or centimeter same. SI unit of perimeter is meter while of area is m²

• Perimeter of square = 4 × side

• Area of rectangle = length × breadth

• Perimeter of triangle = side + base + side

• Try to solve more such questions to get good hold on it
