Answer:
The new coordinates will be D(1,3) E(0,3) and F(-1,0)
Step-by-step explanation:
As can be seen in the picture, points A and B are moved one point negative in the y-axis, and three in the x-axis. Point C and D will have the same coordinates to form the new triangle.

Answer:
Each playground will be 100 m2. Both playgrounds are 200 m2.
Step-by-step explanation:
Area of square is defined by a × a.
a = length of side. In this case a is 10 m
So, Area = 10 m × 10m
Area = 100 m2 (square meters). This is the area of one playground.
Two playgrounds will be the double, 200 m2

Answer:
a. 277.3 m²
b. $307.86
Step-by-step explanation:
a. Area of the wall to be painted = area of rectangle - area of triangle
= L × W + ½×a×b×sin θ
L = 17 m
W = 14 m
a = 8.7 m
b = 9.5 m
θ = 72°
Plug in the values into the equation
Area of the wall = (17×14) + (½*8.7×9.5×sin 72)
Area of the wall = 238 + 39.3024105
Area of the wall to paint ≈ 277.3 m²
b. 20 liters of paint of 1 container cost $21.99
If 1 liter of paint covers 1m², therefore,
277.3 m² will need = 277.3 × 1 = 277.3 liters of paint.
20 liters = 1 container of paint
277.3 liters = 277.3/20 = 13.865 ≈ 14 containers
1 container = $21.99
14 containers = 21.99 × 14 = $307.86
