Answer:

$\boxed {\tt 20 \ meters}$

Explanation:

The perimeter of a rectangle can be found using the following formula.

p= 2l+2w

We know the perimeter is 60 meters and the length is 10 meters.

$p=60 \ m$

$l= 10 \ m$

Substitute the values into the formula.

$60 \ m = 2(10 \ m) + 2w$

Multiply 2 and 10.

$60 \ m = 20 \ m +2w$

Subtract 20 from both sides of the equation.

$60 \ m - 20 \ m = 20 \ m - 20 \ m +2w$

$60 \ m - 20 \ m =2w$

$40 \ m = 2w$

Divide both sides of the equation by 2.

$(40 \ m)/(2) =(2w)/(2)$

$(40 \ m)/(2) =w$

$20 \ m =w$

The width of the rectangle is 20 meters.
