Area is the region occupied by a shape. Perimeter is total distance covered by the boundary of a shape. Area is measured in square units (m2, cm2, in2, etc.) Perimeter is measured in units (m, cm, in, feet, etc.) Example: Area of rectangular ground is equal to product of its length and breadth.
Area Definition (Illustrated Mathematics Dictionary) Definition of. Area. more ... The size of a surface. These shapes all have the same area of 9: Examples: The amount of space. • inside the boundary of a flat (2D) object such as a circle or square, or. • on the surface of a solid (3D) object such as a sphere or cube.
Let's break the area into two parts: Part A is a square: Area of A = a 2 = 20m × 20m = 400m 2. Part B is a triangle. Viewed sideways it has a base of 20m and a height of 14m. Area of B = ½b × h = ½ × 20m × 14m = 140m 2. So the total area is: Area = Area of A + Area of B = 400m 2 + 140m 2 = 540m 2. Sam earns $0.10 per square meter.

So the area here for the purple figure, we could say, so the area here is equal to 10. 10 square, 10 square units. So what we have here, we have an idea of how much space does something take up on a surface. And you could eyeball it, and say, hey, this takes up more space. But now we've come up with a way of measuring it. We can define a unit ...
