7 Ways to Find the Area of a Shape – wikiHow
23 mai 20232. Multiply the sides. Multiply the sides by each other. [2] For example, if you have a rectangle with a height of 16 in and a width of 42 in, you’ll need to multiply 16 x 42. [3] If you’re calculating the area of a square you can actually save yourself some time when using a calculator and just square the side.

A sector of a circle is essentially a proportion of the circle that is enclosed by two radii and an arc. Given a radius and an angle, the area of a sector can be calculated by multiplying the area of the entire circle by a ratio of the known angle to 360° or 2π radians, as shown in the following equation: area =. θ. 360.

18 janv. 2024Simply speaking, area is the size of a surface.In other words, it may be defined as the space occupied by a flat shape. To understand the concept, it’s usually helpful to think about the area as the amount of paint necessary to cover the surface.Look at the picture below – all the figures have the same , 12 square units:

About. Transcript. Perimeter is the distance around the outside of a shape. For example, if you walk around the edge of a playground, you’re measuring its perimeter. Area is the amount of space inside a shape. For example, if you want to put new tiles on your kitchen floor, you need to know the area of the room to know many tiles to buy.

It makes it a little bit clearer than that blue. 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 …

The figure is composed of an equilateral triangle, a rectangle, and a semi-circle (half of a circle). Using the formula for the area of an equilateral triangle and side length 10: The length and width of the rectangle are 10 in and 4 in respectively, so its area is. A = 10×4 = 40. The area of the semi-circle is one-half the of a circle.

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.
