Answer:

The area of triangle is
3.42 \mathrm{ft}^(2)

Step-by-step explanation:

We are given two sides of a triangle and their including angle.

The two given sides of a triangle are , one is 2.7 ft and other is 3.4 ft

And the including angle is given to be 40°

The formula to find area of triangle when two sides and their including angle is given is-

=
(a b \sin \theta)/(2)

where a and b are two sides and θ is the including angle.

Substituting the given values,

Area =
(2.7 * 3.4 * \sin 40^(\circ))/(2)

=
(2.7 * 3.4 * 0.74)/(2)

= 3.42

Hence
3.42 \mathrm{ft}^(2)
is the area of triangle.

Answer:

Area of the triangle
\simeq 5.9 sq. ft. .

Step-by-step explanation:

Length of two sides of the triangle are, 2.7 feet and 3.4 feet and the angle between them is 40° .

So, the area of the triangle is given by,


2.7 * 3.4 * \sin {40^(\circ)} sq. ft.


\simeq 5.9 sq. ft.
