Answer:

\boxed{Area = 32.5 mm^2}

Step-by-step explanation:

Area of Triangle = \frac{1}{2} (Base)(Height)

Where base = 13 mm, Height = 5 mm

Area = 1/2 (13)(5)

=> Area = 1/2 (65)

=> Area = 32.5 mm^2

Answer:

c. 32.5 mm²

Step-by-step explanation:

The equation for the area of a triangle is a=1/2bh. In this equation you basically multiply the length of the base of the triangle times the height of the triangle and divide that by 2 to get the area. So, you would take 13, the base, and multiply it by 5, the height to get 65. Then, you would divide that by 2 to get 32.5 mm².

e-lub [12.9K]

Answer:

          -19

Step-by-step explanation:

                     ~ Distribute:

               - 11 = 1 / 2 x + -3 / 2

                        ~ Flip the equation:

                  1 / 2 x + -3 / 2 = -11

                          ~ Use transposition method:

                     (take -3 / 2 to the other side)

                       1 / 2 x = -11 - (-3 / 2)

                                  = -19 / 2

                                x = -12 / 2 * 2

                                    = -19

Hope this helped
