The scale drawing of a field in the shape of a triangle is shown below

70 m^2.

Step-by-step explanation:

Area of the triangle = 1/2 * base * height.

Counting the squares on the  coordinate plane:

Base = 7, height  = 5

Each square = 2 meters

So the area = 1/2 * 14 * 10

= 70m

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
