Step-by-step explanation:

Area of a triangle = 1/2 base x height

Area of a rectangle = length x breadth

The triangle has 4km and 8km

1/2 x 8 x 4 = 32÷ 2 = 16km². area of a triangle

7km x 9km = 63 km²

The surface area is basically everything joined together making it

area of a triangle x area of a rectangle = 16km² x 63km² = 1,008km².

Eduardwww [97]

Answer: Choice #2

Step-by-step explanation: The slope of -1/4 means that the line is ascending to the left, which rules out the first and last choice. The y-intercept of -3 means that it crosses the y-axis at (0,-3). This is why it is #2.
