The length of the rectangle is 3.1 feet.
Given that, the area of a rectangular painting is 13.02 square feet. The width is 4.2 feet.
We have to find the length. Now, we know that, area of the rectangle is the product of its length and breadth i.e.
where l is the length of the rectangle and b is breadth of the rectangle.
Here, area = 13.02 square feet; b = 4.2 feet
On substituting in the formula we get,
Hence, the length is 3.1 feet.
the correct answer is 828.07
