What is the area of a rectangle that has a length of 9 cm and a width of 4 cm?
The area of a rectangle is always length multiplied by width. Therefore, the area of the mentioned rectangle is 36cm2.
If two rectangle have the same area must they have the same perimeter?
Not always because a 2 by 12 rectangle will have the same area as a 4 by 6 rectangle but they both will have different perimeters.
What is always true about the area of a rectangle?
You can always find the area of a triangle - by dividing the length of the base by 2, then multiplying that figure by the height.
How do you find the area of an odd shape?
There are many ways to find the area of an odd shape. Usually, you have to break the shape down into shapes that you can calculate the area of, and then add the areas of all of those individual shapes to get the area of the entire odd shape.Example:_____|_____\There is no way to find the area of this figure, so you have to break it down into two, easy to find shapes.____|___|\You can see that there is a rectangle and a triangle. You can easily find the area of a rectangle with L X W, and a triangle with 1/2(b)(h). Since it is impossible to find the area of that irregular quadrilateral in one equation, you have to split it into two known shapes (the rectangle and triangle), find the area of each, and then add the areas together to get the area of the entire piece.
Can the sides of a rectangle be negative numbers and therefore have a positive area?
No. Measurement of length of rectangle sides is always a positive number in Euclidean geometry.
