(05.01)Which equation can be used to calculate the area of the shaded triangle in the figure below?

Equation of shaded triangle is .

Solution:

Length of the rectangle = 14 ft

Breadth of the rectangle = 8 ft

Area of the rectangle = length × breadth

                                    = 14 × 8

In this rectangle the diagonal splits the rectangle into two equal halves.

Area of the shaded triangle = Half of area of rectangle

Area of the shaded triangle =

Hence the equation can be used to calculate the area of the shaded

triangle is .
