Answer 1

Answer:

Step-by-step explanation:

Use the formula for the area of a triangle,

Area of a triangle = $\frac{1}{2}(\text{Base})(\text{Height})$

7). Area of the triangle = $\frac{1}{2}(20)(7.4)$

                                       = 74 km²

8). Area of the triangle = $\frac{1}{2}(4)(15.4)$

                                     = 30.8 cm²

9). Area of the triangle = $\frac{1}{2}(16)(7)$

                                      = 56 m²

10). Area of the triangle = $\frac{1}{2}(11)(7.7)$

                                       = 42.35 km²
