Upper primary school mathematics question UPQ113

The figure below is a parallelogram. When the shaded triangle is cut off, the remaining area is 42 cm^{2}. What is the area of the shaded triangle?

Solution:

Cutting of the shaded triangle, give you a rectangle

The area of the rectangle = 42cm^{2}

Given the length of the rectangle = 14cm

The breadth of the rectangle = 42 ÷ 14 = 3cm

The area of the triangle = 3 × 2 ÷ 2 = 3cm^{2}
