Step-by-step explanation:
the formula for the area of a rectangle is
length × width
so, in our case
317.75 = length × 15.5
length = 317.75 / 15.5 = 20.5 m
Answer:

Answer:
Step-by-step explanation:
2/3
1/2
4/5
Multiply the equation 2x + y = 1 by 3 to obtain same coefficients of y.
Substract the equation 3x + 3y = 15 from 6x + 3y = 3 to eliminate the terms of y.
Substitute -4 for x in the equation 2x + y = 1 to obtain the value of y.
So solution of equations is (-4,9).
