Answer:
P = 12m
A = 6m^2
Step-by-step explanation:
Perimeter is the sum of all the lengths of a shape. The lengths of the triangle are given as 3m, 4m, and 5m, so to find the perimeter we just need to add them all together. 3+4+5=12, so the perimeter of the triangle is 12m.
The area of a triangle is found by multiplying its height by its base and then dividing the result by 2. The height of the triangle is not given, but the side lengths (3,4 and 5) indicate that the triangle is a right triangle. This means we can use the middle length as the height and the shortest length as the base.
So, the height of the triangle is 4m, and the base is 3m, so to calculate the area:
(3x4)/2=12/2=6m^2.
The area of the triangle is 6m^2.

Here is the equation: x+(x+20) = 120
Since you can't combine anything yet, its x+x+20=120
You need to get x by itself
Minus 20 from both sides
Its x+x=100 now
Combine the x's which is now 2x
Now divide 100 by 2 which is 50
x=50
---------------
Lets check:
50+(50+20)=120
Now combine the numbers in the parentheses
Its now 50+70=120
50+70=120 and 70-50=20
As you can see, he ran 50 minutes the first day and 70 minutes the second day
