Upper primary school mathematics question UPQ113
The figure below is a parallelogram. When the shaded triangle is cut off, the remaining area is 42 cm2. What is the area of the shaded triangle?
Cutting of the shaded triangle, give you a rectangle
The area of the rectangle = 42cm2
Given the length of the rectangle = 14cm
The breadth of the rectangle = 42 ÷ 14 = 3cm
The area of the triangle = 3 × 2 ÷ 2 = 3cm2
