Question

a scale drawing of a rectangular park had a scale of 1 cm = 70 m. 3.6 cm 10.7 cm what is the actual area of the park in meters squared?

Explanation:

Step1: Find the actual length

Given 1 cm = 70 m, for a length of 10.7 cm on the scale - drawing, the actual length $l$ is $l = 10.7\times70=749$ m.

Step2: Find the actual width

For a width of 3.6 cm on the scale - drawing, the actual width $w$ is $w = 3.6\times70 = 252$ m.

Step3: Calculate the actual area

The area of a rectangle is $A=l\times w$. Substitute $l = 749$ m and $w = 252$ m into the formula, so $A=749\times252 = 188748$ m².

Answer:

188748
