The scale length is 9cm and the scale is 6cm/15ft which is 3cm/5ft, so we can say:

9cm(5ft/3cm)=15ft for the length

If you wanted the width too...

4cm(5ft/3cm)=20ft/3 (6'8", 6ft 8in)

Mathematics

A = 71.5 degrees (1 dp)

cos(A) = (21^2 + 16^2 - 22^2) / (2 x 21 x 16)
= 0.31696...
A = cos^-1(0.31696...) = 71.5 degrees
