Answer :
Answer: width of the garden is 42
Step-by-step explanation:
let's say "x" = the garden's length
and "y" = the garden's width
the length of the garden is 10 feet longer than its width
x-10=y
the garden's perimeter is 188 feet
we can set up a new equation like this:
2x+2y=188
now we have two equations and we can solve using the system of equations.
x-10=y
add 10 on both sides to isolate "x"
x=y+10
2x+2y=188
substitue x for y+10 in the second equation
2(y+10)+2y=188
expand
2y+20+2y=188
combine like terms
4y+20=188
subtract 20 from both sides
4y=168
divide by four on both sides
y=42
the width of the garden is 42 feet
