A table-top measures 2 m 25 cm by 1 m 50 cm. What is the perimeter of the table-top?

Solution:

Given: Measurements of a tabletop is 2 m 25 cm by 1 m 50 cm

Since the tabletop has dimensions of 2 m 25 cm by 1 m 50 cm, it is in rectangular form.

We know that, Perimeter of a rectangle = 2 (Length + Breadth)

Length = 2 m 25 cm, Breadth = 1 m 50 cm

Let's convert the length and breadth to have the same units.

Length = 2 m + 25 cm = 2 × 100 cm + 25 cm = 200 cm + 25 cm = 225 cm

Breadth = 1 m + 50 cm = 100 cm + 50 cm = 150 cm

Thus, Length = 225 cm, Breadth = 150 cm

Substitute these values in the formula of the perimeter of a rectangle.

Perimeter of table-top = 2 (Length + Breadth)

⇒ 2 (225 + 150)

⇒ 2 × 375

⇒ 750 cm

Therefore, the perimeter of the table-top is 750 cm or 7.50m
