Answer:
11 sq units
Step-by-step explanation:
(6×4) - ½(6×1 + 4×3 + 2×4)
= 24 - ½(6+12+8)
= 24 - ½(26)
= 24-13
= 11 sq units
Coordinates will show the vertices of the triangle, and using the vertices, calculate length of the sides of the triangle.With the side length you can now calculate the angles of the triangle.
Step-by-step explanation:
The coordinates of the triangle can be plotted on a graph tool to give you the exact shape.Then using the coordinates that represent vertices for the triangle, apply the distance formula; 
This gives the length of the sides of the triangle.With the side length values, you can apply the cosine rule : c²=a²+b²-2ab cos c to find the angles in the triangle.

Denote by M the point of intersection of the medians.
Denote also the distance DM by x and the distance QM by y.
From the median properties of triangles we know that

Also,

Since the medians are perpendicular, we deduce that:

Then, since
Des Moines - 40F
Austin Carson City - 42F
Jackson - 73F
Find the perimeter of the painting because that's what the frame will be:
2(5)+2(6)=P
10+12=P
22=P
Multiply 22 by 5 because the painting has a perimeter of 22 feet and each one foot will cost 5 dollars
22*5=110
The frame would cost $110
