Question

The perimeter of a rectangular field is 336 m. If the length of the field is 89 m, what is its width?​

Answer 1

The length of the field will be calculated as:
P=2(L+W)
P=376
W=89
thus substituting the values in the equation we get;
376=2(L+89)
376/2=(L+89)
solving for L;
188=L+89
L=188-89
L=99 yards
therefore the length is 99 yards

Hope it helps!
