Question

With a ruler, you measure the tennis court on the aerial photograph to measure 19 mm from base-line-to-base-line. A standard regulation tennis court must be 23.77 m from base-line-to-base-line. What's the scale of the photograph?

Answer 1

Scale will be 1:1250

Step-by-step explanation:

We have given that 19 mm on the photograph represent 23.77 m in real

So 1 mm on photograph represent
`(23.77)/(19)=1.5m\ in\ real`

So 10 mm in photograph represent
`1.25* 10=12.5m\ in\ real`

We know that 1 cm = 10 mm and 12.5 m = 12.5×100 = 1250 cm

So 1 cm in photograph represent 1250 cm in real

Now both have same unit as cm

So the scale will be 1:1250
