Answer 1

ANSWER

D. 32 m

EXPLANATION

We have that the scale of the drawing to the actual lighthouse is 1 cm : 4m.

This means that 1 cm on the drawing represents 4 m in real life.

Converting 4 m to cm (1 m equals 100 cm):

4 m = 400 cm

So, the scale is:

1 cm : 400 cm

This means that to get the actual height of the lighthouse, we have to multiply the length in the drawing by 400.

So, we have:

8 cm * 400 = 3200 cm

Converting this back to metres:

3200 / 100 = 32 m

Therefore, the actual height of the lighthouse is 32 m.
