Answer:
10
Step-by-step explanation:
Recall that the formula for the perimeter of a rectangle is: 2Length+2Width
With this in mind, we have that the original design is 96×60, where 90 is length and 60 is width, so it would simply be:
2(96+l) + 2 (60+w) = New Perimeter
Or simplified, it'd be:
2l + 2w + 312 = New Perimeter
If you would like to know about how far does a car travel in 7.1 seconds, you can calculate this using the following steps:
51.3 feet ... 1 second
x feet = ? ... 7.1 seconds
51.3 * 7.1 = x * 1
x = 51.3 * 7.1
x = 364.23 feet
The correct result would be 364.23 feet in 7.1 seconds.
