3 + 2c³ Finding Areas of Triangles 4c Formula: Area = ½ (base) (height) or ½ bh The height of a triangle is a line that runs from the highest point PERPENDICULAR to the base, meaning that it intersects that base at a right angle. 4c This Is the Height since this is a right triangle Area of this right triangle: Multiply ½ times the base times the height (1/2)(4c)( 3 + 2c³) So (1/2)(4c) = 2c Distribute 2c(3 + 2c³) (2c)(3) + (2c)(2c³) 6c+ 4c⁴ units² 3 + 2c³ LISTEN TO THE EXPLANATION OF HOW TO SOLVE THIS PROBLEM

Find the area and the perimeter of this triangle Find the area and the perimeter of this triangle. This is an isosceles triangle which means it has two sides that are equal. The height of this triangle is given. Formula: Area = ½ (base) (height) or ½ bh Perimeter = distance around To solve for the perimeter, simply add all of the sides: 4x + 4x + 4x +2 = 12x + 2 UNITS To solve for area, multiply ½ times base times height: (1/2)(4x + 2)( y²) (1/2y²) (4x + 2) Distribute:2xy² + y² units² Click here to listen to an explanation of how to solve this problem. 4x 4x Height = y² This is as simple as you can get since you have two different terms you are adding together! 4x + 2
