AREA, PERIMETER, CIRCUMFERENCE

SQUARE

• To find the area of a square you need to multiply
• base times height. Ex. A= B x h, 5 x5= 25
• To find the perimeter, you need to add all of the sides
• together. Ex. 5+5+1+6= 17. The perimeter is 17

RECTANGLE

• The equation to find the area of a rectangle
• Is the same as a square. Multiply base times height
• The perimeter is also the same. Add all sides together .

PARALLELOGRAM

• The way to find thearea of a parallelogram
• is the same as a rectangle and a square.
• B x h. Ex. 4ft x 5ft =20 ft

TRIANGLE

• The equation of the are of a triangle
• is 1/2b x h = a. Ex. 1/2 4 x 6 =
• 1/2 24= 12

TRAPAZOID

• the area of a trapazoid
• Is 1/2(b1 + b2) h. 1/2 (2+3) 2
• 1/2 5x2= 1/2 10. 1/2 10= 5

CIRLCE

• The area of a circle is
• Pi x 2r ( r= radius). 3.14
• x 2(2). 3.14 x 4 = 12.56

CIRLCE CIRCUMFERENCE

• The circumference of a Circle is
• 2pi x radius.
• Ex. 2(3.14) x 2 = 12.56
