A rectangle is a four-sided polygon with four right angles, whose opposite sides are parallel and are equal.
A rectangle is a particular sort of parallelogram, but can't say that all parallelograms would be rectangles, because a rectangle is a shape where opposites sides are parallel and all the corners are 90 degree angles. Some parallelograms would be rectangles, but not all.
Area of a rectangle
The area of a rectangle is the product of its width and length.
What is the area?
Find the base and height of the rectangle.
Use these numbers in the formula.
||= base × height
||= 14 × 24
Now find the units. The lengths are measured in kilometers, so the area is measured in square kilometers.
|The area is
|| square kilometers.
What is the area when b=9, and h=4?
