The area of a rectangle is worked out by the equation axb when a is length and b is width. Thus, if a and b are both integers, a good way to work out possible lengths would be to break down the area into its prime factors. These are 2, 3 and 3. Now any product of these primes for a, and the other prime for b, will work as a possible rectangle.
For example a=2x3=6 and b=3 will work
a=3x3=9 and b=2 will work
Thus possible rectangles are 1x18, 2x9 and 3x6

If The area of a rectangle is 18 units squared and the other rectangle has area 6 units squared what would the ratio of their areas be?
ratio is 18 to 6 which is 3 to 1.
The perimeter of a rectangle is 18 feet and the area of the rectangle is 14 square feet what is the length of the rectangle?
7 feet 2(7+2) = 18 feet 7*2 = 14 square feet
If the area of a rectangle is 18 square inches and the length of the rectangle is twice it's width what is the length and width of the rectangle?
A rectangle with one side that is double the length of the other side can be seen as two squares beside each other, that are half the area of the original rectangle, in this case 18 square inches / 2 = 9 square inches. The side of a square is the square root of the area, in this case the square root of 9 square inches, which is 3 inches. Now think about the rectangle again. What we just counted was the side of a square that made up one half of the rectangle you wanted to calculate the area of. So the shorter side of the rectangle is the same as our square, and the longer side is double the length. So the width of the rectangle is 3 inches, and the length is 2 * 3 inches = 6 inches. Or: Area = length x width (A=lw) Area = 18 (in2) Width = w Length = twice width (2w) 18 = (2w)w 18 = 2w2 9 = w2 3 = w The width is 3 in., the length (2w) is 6 in.
How do you draw a rectangle with an area of 18 square centimeters and perimeter of 18 centimeters?
Draw it with dimensions of (6 cm) by (3 cm).
The length of a rectangle is 4cm longer than its width If the perimeter of the rectangle is 36cm find its area?
Length + width = half of perimeter, ie 18 cm. 18 - 4 = 14, 14/2 = 7 so sides are 7 and 11 cm and area = 77sq cm
What is the area of a rectangle 2cm by 9cm?
The area of rectangle is : 18.0
What is the area of a 30x18 rectangle?
Area of rectangle: 30 times 18 = 540 square units
If A circle and rectangle have the same area the circle has a diameter of 42 centimeters and rectangle has a width of 18 centimeters find the perimeter of the rectangle?
Area of circle = pi*212 = 1385.44236 square cm Area of rectangle = 1385.44236 square cm Lenght of rectangle = 1385.44236/18 = 76.96902 cm Perimeter of rectangle = 2(76.96902)+2(18) = 189.93804 cm
What is the area of a rectangle 12 ft wide and 18 ft long?
The area of rectangle is : 216.0
What is the area of the largest square of a rectangle of 18 by 9?
Not sure if this is what is required, but the area of the largest square that will fit in a 18 by 9 rectangle is 9 by 9.
What is the area of a rectangle that is 6 cm by 3 cm?
area of any rectangle is length x breadth. For a 6x3 rectangle, it's 18.
