Hi there!
We are looking for the circumference of the school field. When we assume that the field is a rectangle, we can use the following formula for finding its circumference.
Circumference = 2 × length + 2 × width
Plug in the length and width from the question.
Circumference = 2 × 50 + 2 × 10
Multiply first (remember: PEMDAS).
Cirxumference = 100 + 20
And finally add.
Circumference = 120.
Hence, the total length of the fence will be 120 meters.
~ Hope this helps you!

Hello there
Step-by-step explanation:
Answer:
100 miles
Step-by-step explanation:
Given :
To work :
speed = 50mph
Let time taken = x
From work :
speed = 40mph
30 minutes = 30/60 = 0.5
Time taken = x + 0.5
Distance from home to work :
Distance = speed * time
To work distance = from work distance
This can be algebraically expressed as :
50 * x = 40(x + 0.5)
50x = 40x + 20
50x - 40x = 20
10x = 20
x = 20/10
x = 2
Hence,
Distance = 50 * 2 = 100
The the distance from home to work = 100 miles
Answer:
a) 25 + 3x =45
b) 3x = 45-25
3x = 20
x = 20/3
x = 6.33
