1 answer:
The rectangle's length is 30 inches while it's width is 24 inches.
Step-by-step explanation:
Step 1; Any rectangle's area is calculated by multiplying the rectangle's length and its width. Assume the the rectangle's length is 5x while it's width is 4x as it is given that the ratio of it's length to width is 5: 4.
Area of the rectangle = 5x × 4x = 720, 20x² = 720.
x² = = 36, x =√36 = 6.
Step 2; As we assumed length equals 5x and the width will equal 4x.
The rectangle's length = 5x = 5 × 6 = 30 inches,
The rectangle's width = 4x = 4 × 6 = 24 inches.

Answer:
The answer to the question is
It would take Lalelyn bout 3 hours to run the 18m miles, and it will take her
and x +y+z =18 where x, y, and z are the distannce covered swimming, running and bikinr respectifully
Step-by-step explanation:
To solve the question, we lisrt out the variables as follows
Swimming speed of Lakelyn = 250 yards every 5 minutes or 250×12 = 3000 yards/hour = 1.7 miles/hr
Running speed of Lakelyn = 6 miles/hour
Biking speed = 12 miles/hour
The duration it will take for Lakelyn to run 18 miles is given by
Timee taken to run 18 miles t = (Distance covered)/ (Speed of Lakelyn))
or t = D/S
Substituting the known values of such as
Running speed of Lakelyn = 6 miles/hour
From which we have the time taken to run 18 miles = 18 miles /(6 miles/hour) = 3 hours
should the 18 miles form part of the triathlon then, we have
and x +y+z =18
Where x, y and z are the distance covered Swimming, Running and Biking respectively
