we have
step 1
Find the distance AB
we have
substitute in the formula
step 2
Find the distance BC
we have
substitute in the formula
step 3
Find the distance DE
we have
substitute in the formula
step 4
Find the distance AE
we have
substitute in the formula
step 5
Find out the area of the four walls
To determine the area sum the length sides and multiply by the height of the walls
so
substitute the given values
The height of the walls is 10 ft
step 6
Determine the number of gallons needed to paint the four walls
we know that
one gallon of paint is enough to cover 400 square feet
using proportion

= 12/5
Answer:
Note that both the x and y coordinates are multiplied by the SAME value, k. Given ΔDEF with center of dilation the origin (0,0) and scale factor of 2, plot ΔD'E'F'. As shown in the formula above, multiply each x and y coordinate value by the scale factor of 2 to find the new coordinates
