Mass of freight train: 9.98 • 106
= 1057.88 kg
mass of aircraft carrier: 7.3 • 107
= 781.1 kg

= 276.78 kg
= 2.7678 x 10^2

Answer:
The length of the rectangular playing field is 84 yards and the width is 44 yards
Step-by-step explanation:
Let
x ------> the length of the rectangular playing field
y -----> the width of the rectangular playing field
we know that
The perimeter of the rectangular playing field is equal to


so
------> equation A
we have that
-----> equation B
Solve the system by substitution
Substitute equation B in equation A and solve for y





Find the value of x

therefore
The length of the rectangular playing field is 84 yards and the width is 44 yards
