24 cm is.

Area: 15ab Perimeter: 2(3a+5b) or as 6a+10b

To find the area of a rectangle, you multiply the length by the width (one side by a different side) Or you could count how many centimeter squares make up the rectangle

Infinitely many shapes have a perimeter of 28 and an area of 18. A rectangle that has those qualities has one side about 1.432 and the other about 12.568

Area = 35 cm2 and one side = 5 cm => other side = 7 cm So perimeter = 2(5 + 7) = 2*12 = 24 cm

You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.

This question has no unique answer. A (3 x 2) rectangle has a perimeter = 10, its area = 6 A (4 x 1) rectangle also has a perimeter = 10, but its area = 4 A (4.5 x 0.5) rectangle also has a perimeter = 10, but its area = 2.25. The greatest possible area for a rectangle with perimeter=10 occurs if the rectangle is a square, with all sides = 2.5. Then the area = 6.25. You can keep the same perimeter = 10 and make the area anything you want between zero and 6.25, by picking different lengths and widths, just as long as (length+width)=5.

For any given area, the rectangle closest to a square will have the smallest perimeter; and the one that is most "stretched out" has the largest perimeter. In this case, that would be a width of 1 and a length of 2014.

One side 8 long, other side 3 long.

No. The length is the measurement of the distance from the bottom to the top of the rectangle, or from one side to the other side. The perimeter is the distance all the way around the rectangle.

i think that the biggest one would be 1x100 (area) and 202 (perimeter) but i am not sure

Only if you have one additional piece of information, such as that it is a rectangle or a triangle, or that all sides are equal.
