Area of a Triangle
Definition of the Area of a Triangle – Example 1 Definition of the Area of a Triangle – Example 2 Find the area of this triangle. Solution:Step 1: Multiply the base by the height. \(14×8=112\)Step 2: Multiply \(\frac{1}{2}\) by the result. \(\frac{1}{2}×112=56\)So, the area of the triangle is \(56 cm^2\).Area\(=\)base\(×\)height\(×\frac{1}{2}→A=\frac{1}{2}(b×h)→A=\frac{1}{2}(14×8)=56\)
Area of a Parallelogram
Definition of the Area of a Parallelogram – Example 1 Definition of the Area of a Parallelogram – Example 2 What is the area of this parallelogram? Solution:To determine the area of a parallelogram:Multiply the base by the height. \(9×4=36\)So, the area of a parallelogram is \(36 cm^2\).Area\(=\)base\(×\)height→\(A=b×h→A=9×4=36\)
