Question

A poster has an area of 5250 square centimetres.

What is the area of the poster in square millimetres?

Worked Solution

Solution 1:

One example of the dimensions of a 5250 cm2^2

rectangle = 525 cm ×\times 10 cm

Converting to millimetres:

5250 mm ×\times 100 mm = 525 000 square millimetres


Solution 2:

Scale factor of converting cm to mm = 10

Scale factor of converting cm2^2 to mm2^2 = 10 ×\times 10 = 100

∴\therefore 5250 cm2 ×^2\ \times 100 = 525 000 mm2^2
