A rectangle is 7 feet long by 4 feet wide. If 4 feet are removed from the length of the rectangle, what would be the area, in square feet, of the new rectangle?

The original length is 7 feet, so, subtract by 4 to find the new length.

7 - 4 = 3 feet

Now, find the area with the new length [ A = lw ]

A = 3*4

A = 12

Therefore, the area of the new triangle is 12ft².

Best of Luck!
