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
`(1)/(2) (14*8)`.

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

`$=(1)/(2) (14*8)`

Area of the shaded triangle =
`(1)/(2) (14*8)`

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

triangle is
`(1)/(2) (14*8)`.
