The ratio of the lengths of the two rectangles is 12 feet to x feet. The ratio of the widths of the two rectangles is 2 feet to 5 feet.
To find the missing measure (x), we can set up a proportion:
12 feet / x feet = 2 feet / 5 feet
Cross multiplying, we get:
12 * 5 = 2 * x
60 = 2x
x = 30 feet
Therefore, the missing measure on the big rectangle is 30 feet.
The small rectangle was enlarged to create the big rectangle.
A smaller rectangle has a length of 12 feet and width of 2 feet. A larger rectangle has a length of x feet and width of 5 feet.
