the perimeter of a rectangle room is 60 feet. let x be the width of the room (in feet) and let y be the length of the room (in feet). select all of the questions below that could modle this situation

Sagot :

Given that,

The perimeter of a rectangle is 60.

The perimeter is generally defined as the length of the outline of the shape.

So, in rectangle having four sides, the perimeter would be sum of all the sides.

Length1 + length2 + length3 + length4 = perimeter

Here, length1 and length3 are equal, that are the lengths (y),

Similarly,

Length2 and length4 are equal, that is width (x).

Hence, the equation becomes,

x + y + x + y = perimeter

or

2x + 2y = 60

or

2 (x + y) = 60

Hence, the first two options are correct.
