Yes you do need to write this.Area and Perimeter Yes you do need to write this.
AREA The amount of space inside a 2-dimensional object.Measured in square units cm2, m2, mm2 Not to be confused with……
Perimeter The distance around a two dimensional object.Measured in ‘normal’ units eg. cm, m, mm
Some shapes have there own formulas for areaYes, you do need to draw these as well.
Rectangle b a Area of a rectangle = ab (length x width)Perimeter = 2a + 2b = 2(a + b)
No, you don’t have to try one.
Parallelogram a b ‘a’ is the vertical height Parallelogram – quadrilateral with two pairs of parallel sides. Area = ab Can not work out the perimeter with the information given.
One to try 6cm 7cm Area = 6 x 7 =42 cm2
Triangle Area = ½ bh ( ‘h’ is the vertical height)b b
Trapezium (a quadrilateral with one pair of parallel sides)b Add together the parallel sides, divide by 2 and then multiply by the distance between them. Area = (a + b) x h 2
Example 2cm 10cm 5cm Area = (2 + 5) x 10 2 = 3.5 x 10 = 35 cm2
Compound Shapes These are shapes made by joining two or more shapes together. To find the area, find the area of the smaller shapes and add together.
Example. 7cm 10cm 8cm 3cm 7cm 2cm 8cm 3cm X Y
Example. Area of X = 7 x 2 = 14 cm2 Area of Y = 3 x 8 = 24 cm2Total area = = 38 cm2 7cm 2cm 8cm 3cm X Y
Last one. Find the shaded area10cm Area of square = 10 x 10 = 100 cm2 A. of triangle = ½ x 3 x 4 = 6 cm2 Shaded area = 100 – 6 = 94 cm2 3cm 3cm 4cm
The only part left is circles (always a circle question)And then it’s volume.
Area & Perimeter An Introduction. AREA The amount of space inside a 2-dimensional object. Measured in square units cm 2, m 2, mm 2 Example: 1 cm 2 cm.
The distance around an enclosed shape is called the perimeter. The amount of space enclosed inside a shape is called the area.
Perimeter and Area Formulas. Perimeter is the distance around an object. It is easily the simplest formula. Simply add up all the sides of the shape,
Area & Perimeter Learning Objectives: 1.Learn to find perimeter and area of simple & compound/composite shapes. 2.Practice solving problems involving area.
What is area? The amount of space that a figure encloses The number of square units that covers a shape or figure. It is two-dimensional It is always.
Perimeter & Area Lessons 19 & 20. Vocabulary Perimeter The OUTSIDE (total) area of a polygon Area The INSIDE area of a polygon.

Area. The amount of surface covered by each shape is called its area. Which one of these carpets takes up more floor space? They have the same area.
Area of Quadrilaterals and Triangles. What is a quadrilateral? Any polygon with four sides and four vertices (or corners) All sides must be straight.
