The area A of a triangle is given by the formula:A=12×base×heightSubstituting the values we have:600=12×(x+10)×x Step 3: Simplify the EquationMultiply both sides by 2 to eliminate the fraction:1200=(x+10)×xExpanding the right side:1200=x2+10x Step 4: Rearrange the Equation...
Example: What is the area of a triangle with base 'b' = 2 cm and height 'h' = 4 cm?Solution: Using the formula: Area of a Triangle, A = 1/2 × b × h = 1/2 × 4 × 2 = 4 cm2Triangles can be classified based on their angles as acute, obtuse, or right triangles. ...
