Question

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

Answer 1

Equation of shaded triangle is $\frac{1}{2} (14\times8)$.

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

                                              $=\frac{1}{2} (14\times8)$

Area of the shaded triangle = $\frac{1}{2} (14\times8)$

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

triangle is $\frac{1}{2} (14\times8)$.
