The answer is 24. There is 2 width sides and 2 length sides. Let's say the width measurement is x. The 2 sides for width equals 2x. The 2 length sides equals 4x because there twice has long has the width which means that each length side is 2x. 2x plus 4x equals 6x. 6x=24 You divided 24 with 6 which gives you 4. That means that both width sides are 4 units long and the length sides are 8 units long. 4+4+8+8=24, 4 times 8=24

Answer:

x = 20

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{x}{12}$ = $\frac{15}{9}$ ( cross- multiply )

9x = 180 ( divide both sides by 9 )

x = 20

If you are driving 20 meters per second, what would be the equivalent of that in miles per hour?

melomori [17]

$\frac{20 meters}{1 second} \frac{60 seconds}{1 minute} \frac{60 minutes}{1 hour}$

the fractions are set up so that each unit cancels out until its only meters/hour

you can multiply all the numerators together to get 72000 and all the denominators to get 1

72000 meters/1 hour

72000 meters in 1 hour

hope this helped
