### A rectangle has primeter 20mexpress the area of the rectangle as a function of the length of one of its side?

If the perimiter is 20 and one side is [[length]] then the other side is (10 - [[length]]). So the area is: [[length]] x (10 - [[length]]) square metres.

### How do you find the unknown side of a rectangle if you have the area and one side?

Divide the area by the known side.

### If you double the side lengths of a rectangle why is the area of the new rectangle not twice as big as the original?

Look at it this way, suppose x is one side of the rectangle and y is the other. Then the area of the rectangle would be xy. Now if you double each side of the originial rectangle you would have each side as 2x and 2y. So the area of the new rectangle would be 2x*2y or 4xy. As you can see the new area is 4 times larger than the original.

### How can you draw a rectangle that has an area of 24 and a perimeter of 22?

One side 8 long, other side 3 long.

### How is the area of a rectangle and a parallelogram the same?

A parallelogram is just a rectangle leaned to one side

### If the area of a rectangle is 12x2 - 19x - 21 and one side is 4x - 3 what is the other side?

Since the area of a rectangle is equal to the product of its two sides, then 4x - 3 is one factor of the product 12x^2 + 19x - 21 which represents the area. So the other factor is 3x + 7. Check: Or the given side could be 4x + 3 and the other side is 3x - 7, in order to obtain the area 12x^2 - 19x - 21.

### What is the area of a rectangle with a side of8 and diagonal of 10?

Area = length x width. You have one of the sides; to get the other side, use the Pythagorean Theorem. Then multiply the two sides.

### How do you write simplified expressions for the area and the perimeter of a rectangle one side 3a other side 5b?

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

### Can you find the area of a rectangle only knowing the perimeter?

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
