Perimeter of a rectangular room is 270 yards. longer side of the room is 15 yards longer than the shorter side. find the dimensions of the room.

In this question , it is given that, Perimeter of a rectangular room is 270 yards. Longer side of the room is 15 yards longer than the shorter side.

So if we let shorter side be x, then longer side is

And perimeter is equal to sum of all sides, that is

So the smaller side is 60 yards , and longer side is 15 more then 60 that is 75 yards .

The shorter side is 20 yards and the longer side is 35 yards.

Step-by-step explanation:

Since we have given that

Perimeter of a rectangular room = 270 yards

Let the shorter side be 'x'.

Let the longer side be 'x+15'.

As we know the formula for perimeter:

Perimeter is given by

So, the shorter side is 20 yards and the longer side is 20+15=35 yards.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
