Question

town is building a pool based on a scale drawing that is 20 centimeters by 10 centimeters and uses the scale 1 cm : 250 cm. What is the area of the pool in square meters

Answer 1

The area of he pool is 1250 sq. meters.

Explanation:

Here, the dimensions of the pool in the drawing are:

Length = 20 cm

Width = 10 cm

Now, SCALE is 1 cm = 250 cm

⇒ The actual dimensions of the pool are

Length' (L') = 20 cm x 250 = 5000 cm

Width' (W') = 10 cm x 250 = 2500 cm

Now, 1 m = 100 cm

⇒ 5000 cm = (5000 /100) m = 50 m

and 2500 cm = (2500 / 100) m = 25 m

AREA OF THE RECTANGULAR POOL = LENGTH' x WIDTH'

= 50 m x 25 m

= 1,250 sq m

Hence, the area of he pool is 1250 square meters.
