The area of a rectangle is 56 square inches The width of the rectangle is 7 in What is the length?
Area = LxW Using the figures you have 56 = L x 7 L = 56/7 L = 8
How do you prove the formula for the area of a rectangle?
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
How do you find the perimeter of a rectangle when given area?
You cannot. There are infinitely many possible answers.Given Area = A square units, select any value of L > sqrt(A) units and let B = A/L units.Then for every one of the infinitely many values of L, the rectangle with length L and breadth B, the area = L*B = L*(A/L) = A square units.The reason for selecting L > sqrt(A) is simply to ensure that each different value of L gives a different rectangle and you do not have the length and breadth of one rectangle being the breadth and length of another.You cannot.

The length of a rectangle is five times its width if the perimeter of the rectangle is 72 ft find its area?
L = 5W 2L + 2W = 72 ==> L + W = 36 Substitute L = 5W: 5W + W = 6W = 36. ==> W = 6, and L = 30. Area = 180
How do you work out area of half a rectangle?
Find the area of all of it, then devide by 2.
