The base length of a triangle is 12 feet and the height is 6 feet. what is the area of the triangle?

10 square feet
12 square feet
18 square feet
36 square feet

36 square feet

Step-by-step explanation:

The area of a triangle is half the area of a rectangle.

Formula;

Area =  1/2 bh

Where b is ta the base length and h is the perpendicular height to the base length.

Area = 1/2 × 12 ×6

      = 6 × 6

       = 36 feet²

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
