Answer:

The actual height is 150ft

Step-by-step explanation:

Given

$Width : Height = 2cm : 5cm$

$Actual\ width = 60ft$

Required

Determine the actual height

Substitute 60ft for width in: $Width : Height = 2cm : 5cm$

$60ft:Height =2cm:5cm$

Express as fraction

$\frac{60ft}{Height} =\frac{2cm}{5cm}$

$\frac{60ft}{Height} =\frac{2}{5}$

Make height the subject

$Height = \frac{5}{2} * 60ft$

$Height = 5 * 30ft$

$Height = 150ft$
