Question

A rectangular tennis court is 8 m wide and 20 m long. A scale plan is drawn

with a width of 4 cm. If the scale plan is an accurate model, what is its
length? (Hint: 1 m is 100 cm)
Please answer

Answer 1

The length in the draw is 10 cm

Explanation:

step 1

Find the scale plan

Divide the width in the draw by the width in the real

so

`(4)/(8)=(1)/(2)(cm)/(m)`

That means----> 1 cm in the draw is equal to 2 m in the real

step 2

Find the length in the draw

using proportion

`(1)/(2)(cm)/(m)=(x)/(20)(cm)/(m)\\ \\x=20/2\\ \\x=10\ cm`
