Learning Unit 13: Area of \u200b\u200bplane figures

Here you can access a given task that will help you to learn the concepts related to this unit.

OBJECTIVES:
• Calculate the area of \u200b\u200bsquares, rectangles, rhombuses, rhomboids and triangles.
• Calculate the area of \u200b\u200bregular polygons.
• Calculate the area of \u200b\u200bcircles.
• Calculate the area of \u200b\u200bplane figures, breaking them down into areas known figures.
• Solve problems by reducing them first to another known.

MUST LEARN:

Area of \u200b\u200brectangle: is calculated by multiplying its base by its height.
Area of \u200b\u200bsquare: is calculated by multiplying the side itself. Area
diamond: the product of its diagonal diagonal less divided by 2.
rhomboid area: the product of its base by its height.
Triangle Area: is the product of its base by its height divided by 2.
area of \u200b\u200bregular polygons: the product of its perimeter by its apothem divided by 2. Area
circle: it is the product of the number π by its radius squared.
area of \u200b\u200ba plane figure : we must first decompose other figures whose areas we know to calculate and then sum the areas of these figures.
