Question

Brody’s town is building a pool based on a scale drawing that is 20 centimeters by 10 cemtimeters and uses the scale 1 cemtimeter : 250 cemtimeters. What is the area of the pool in square meters?

Answer 1

Answer:

Area of the pool is 1250 square meters.

Step-by-step explanation:

Given:

1 cm on scale is 250 cm in actual.

Therefore, 20 cm on scale is $20\times 250 = 5000\textrm{ cm}$

10 cm on scale is $10\times 250 = 2500\textrm{ cm}$

Also, we know that, $1\textrm{ cm}= \frac{1}{100}\textrm{ m}$

Therefore,

$5000\textrm{ cm}=5000\times \frac{1}{100}=50\textrm{ m}\\2500\textrm{ cm}=2500\times \frac{1}{100}=25\textrm{ m}$

Area of the pool is given as,

$Area=50\times 25=1250\textrm{ }m^{2}$

Therefore, the area of the pool is 1250 square meters.
