Simon runs an SME and is looking for a bigger office space.
On a scale drawing, a building he is considering has a length of 12.4cm and a width 9.4cm.
The real length of the building is 62 metres.
Work out in metres the real width of the building.
Answer:
Since it’s a scale drawing we can set out the distances we know in ratios of length : width.
12.4 : 9.4 62 : ?
To workout the missing width we can determine the multiplier used between the ratios by doing 62/12.4 which is 5. That means the drawing is done at a scale of 5 times smaller.
We can use the same principle to find the actual width by multiplying the scaled width by 5.
9.4 x 5 = 47 metres
