So to solve this, from the given statements, we know that the length is equivalent to twice the width minus 15 and our width is just wheat.
00:18
And we are given with a rectangle.
00:22
Therefore, we will use the formula in finding the perimeter of our rectangle, which is twice the sum of its length and the width.
00:32
So we substitute our given which is 2 l is equivalent to 2 w minus 15 inches and then we add the width.
00:44
And our perimeter is given as 60 inches.
00:49
So let's write here 60.
00:51
Now solving for this we will have 60 and 2 .2 plus w would be 3w minus 15.
01:02
So bring this further, we have 2 times 3 w would be 6w minus 2 times 15 or negative 15 is negative 30 and it's a negative sign.
01:16
And then we will group like terms.
01:19
Let's transfer 30 on the left side so it will have positive sign.
01:24
Then we have here 6w...
