Answer: 34 meters.
Step-by-step explanation;
Step One. Find the value of the width. Use an equation with w representing the width and the two values you already have. 9 meters x w = 72 square meters.
Step Two. Solve for width. This is w = 8.
Step Three. Use the value for width in a perimeter formula to calculate the perimeter; 9(2) + 8(2). <em>This is 34 meters for perimeter</em>.
Step one. $5.00 - 9 peppermints
= $5.00 - $1.35
= $3.65
Step two. Figure out how many 25 cents are in $3.65.
$3.65 divided by .25
= 14.6 So David can buy 14 sour candies.
Divide the distance by the average speed to find the time. 30 miles 20.04 mph 1.497 hrs. So it would take about 1.5 hours.
