B.15
C.45
D.30
I really need help.
The width of the rectangle is 30 units.
To find the width of a rectangle, we need to use the formula for the perimeter of a rectangle, which is 2(length + width). In this case, we are given the perimeter as 90 and the length as 15. Plugging these values into the formula, we get: 90 = 2(15 + width).
Now we can solve for the width. First, simplify the equation: 90 = 30 + 2(width).
Then, subtract 30 from both sides: 60 = 2(width). Divide both sides by 2 to isolate the width: width = 30.
Therefore, the width of the rectangle is 30 units.
