Answer:15m on each side
Step-by-step explanation:
Answer: 102.9 m
<u>Step-by-step explanation:</u>
First, use Pythagorean to find the length of AC
AB² + AD² = AC²
50² + 80² = AC²
2500 + 6400 = AC²
8900 = AC²
94.34 = AC
Next, subtract 15 (the diameter of the circle) from AC to find the length of the straight line.
94.34 - 15 = 79.34
Next, find the circumference of the circle
C = πd
C = 15π
They are only walking around 1/2 of the circle so divide it by 2.
(1/2)C = (15/2)π
≈ 23.56
Add the straight line (79.34) and the half circumference (23.56) to find the total distance traveled.
79.34 + 23.56 = 102.9

In general we know
1 meter = 1.09361 yard.
So we can say
1 yard =
meter
= 0.9144 meter.
So 120 yards =
meter
= 109.728 meter.
So length of football field is 109.728 meter.
Answer:
20ft × 17ft
Step-by-step explanation:
(20-x)(23-x) = (20×23) - 120
460 - 43x + x² = 460 - 120
x² - 43x + 120 = 0
x² - 40x - 3x + 120 = 0
x(x - 40) - 3(x - 40) = 0
(x - 40)(x - 3) = 0
x = 3, 40
x = 3
