Answer:
Area = 228 m²
Perimeter = 60 m
Step-by-step explanation:
The figure given shows a rectangle that has a cut triangular portion.
✔️Area of the figure = area of rectangle - area of the triangular cut portion
= L*W + ½*bh
Where,
L = 20 m
W = 12 m
b = 20 - (8 + 8) = 4 m
h = 6 m
Plug in the values
Area = 20*12 - ½*4*6
Area = 240 - 12
Area = 228 m²
✔️Perimeter = perimeter of rectangle - base of the triangular cut portion
= 2(L + W) - b
L = 20 m
W = 12 m
b = b = 20 - (8 + 8) = 4 m
Plug in the values
Perimeter = 2(20 + 12) - 4
= 2(32) - 4
= 64 - 4
Perimeter = 60 m
Answer:
60, if they all have the same age, 60 * 3 = 180.
The oldest one has to be aged 60 along with the youngest aged.

Answer:
Please check attached graph.
Step-by-step explanation:
Graph for the answer choices are missing but still we can solve this problem.
We can create graph of y=-x-3 first
then shade the graph for given inequality.
Comparing y=-x-3 with y=mx+b gives slope m=-1 and y-intercept b=-3
so we graph a point at (0,-3) for y-intercept.
then move the point 1 unit down and 1 unit right to reach point (1,-4)
Now join both points by a solid line because of equal sign of >=
this will give graph of y=-x-3
Now we determine direction of shading using any test point which is not on the line y=-x-3
say (0,0) is test point as it is not on the line y=-x-3
plug the test point into original inequality
![y\ge-x-3](https://tex.z-dn.net/?f=y%5Cge-x-3)
![0\ge-0-3](https://tex.z-dn.net/?f=0%5Cge-0-3)
![0\ge-3](https://tex.z-dn.net/?f=0%5Cge-3)
which is true so the direction of shading will be in the direction of test point.
