Question

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

A rectangle with a length of 18 feet and width of 4 feet. A diagonal cuts the rectangle into two halves. One of the triangular halves is shaded.
(1 point)


2(18 + 4) = 44

fraction 1 over 2 (18 + 4) = 11

2(18 × 4) = 144

fraction 1 over 2 (18 × 4) = 36

Answer 1

fraction 1 over 2 (18 × 4) = 36

`\because`Area of standard triangle

`= (1)/(2) * base* height.`

Where,

Base of triangle = lenght of rectangle = 18 feet

&

Height of triangle = width of rectangle = 4 feet
