1 cm
2.5 m
A 12 cm
C: 13 cm
B: 5 cm
Which proportion could Eveline use to find the length of side A?
1 cm
2.5m
13 cm
xm
1 cm
12cm

Answer 1

Answer:

$\frac{1}{2.5}\ \frac{cm}{m}=\frac{12}{x}\ \frac{cm}{m}$

StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 12 centimeters over x meters EndFraction

Step-by-step explanation:

The complete question is

Eveline made a scale drawing of a patio she is planning to build.

1 centimeter = 2.5 meters. Triangle A B C. Side A is 12 centimeters, side B is 5 centimeters, and side C is 13 centimeters.

Which proportion could Eveline use to find the length of side A?

StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 13 centimeters over x meters EndFraction

StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 12 centimeters over x meters EndFraction

StartFraction 12 centimeters over 2.5 meters EndFraction = StartFraction x centimeters over 1 meter EndFraction

StartFraction 1 centimeter over 12 meters EndFraction = StartFraction 2.5 centimeters over x meters EndFraction

The picture of the question in the attached figure

we know that

The scale drawing is

$\frac{1}{2.5}\ \frac{cm}{m}$

That means

1 cm in the drawing represent 2.5 m in the actual

using proportion

Find out the actual length of side A if in the drawing the length is 12 cm

$\frac{1}{2.5}\ \frac{cm}{m}=\frac{12}{x}\ \frac{cm}{m}$

solve for x

$x=12(2.5)\\x=30\ m$

The length of side A is 30 meters

Answer 2

The first answer is so confusing that I'm gonna put the answer as B.
