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
.
