Problem
Area of a triangle is equal to .....of area of a rectangle If they have a common base lying on one of two parallel Straight lines including them
Solution
Step 1 ：\(A_{triangle} = \frac{1}{2} \times b \times h_{triangle}\)
Step 2 ：\(A_{rectangle} = b \times h_{rectangle}\)
Step 3 ：\(\frac{A_{triangle}}{A_{rectangle}} = \frac{\frac{1}{2} \times b \times h_{triangle}}{b \times h_{rectangle}}\)
