The perimeter of the new rectangle can be found by adding up the lengths of all four sides.
Since the length is the same as the first rectangle, it is still 45 inches.
The width of the new rectangle is twice as wide as the width of the first rectangle, which means it is 2*45 = 90 inches.
Now, to find the perimeter, we add up all four sides:
45 + 45 + 90 + 90 = 270 inches
So, the perimeter of the new rectangle is 270 inches.
Elena cuts out a rectangle that has a perimeter of 156 inches and a length of 45 inches. She cuts out another rectangle that is the same length and twice as wide.
