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.
base: |
14 km |
height: |
24 km |
Use these numbers in the formula.
Area |
= base × height |
|
= 14 × 24 |
|
= 336 |
Now find the units. The lengths are measured in kilometers, so the area is measured in square kilometers.
The area is |
336 |
square kilometers. |
