Find the width of a rectangle with a perimeter of 90 and a length of 15.
90
15
45
30
The width of the rectangle can be found by subtracting twice the length from the perimeter:
90 - (2 * 15) = 90 - 30 = 60
Therefore, the width of the rectangle is 60.
To find the width of the rectangle, we can subtract the length from the perimeter and then divide the result by 2 because the perimeter is the sum of all sides of the rectangle.
First, subtract the length (15) from the perimeter (90):
90 - 15 = 75
Next, divide the result (75) by 2:
75 รท 2 = 37.5
Therefore, the width of the rectangle is 37.5. However, since width is typically represented as a whole number, we can round down or up.
Rounded down: 37
Rounded up: 38
So the possible widths of the rectangle could be 37 or 38 (depending on how the rounded number is expressed and the unit of measurement used).
