PLEASE HELP ME WITH THIS! A flower bed is in the shape of a triangle with one side twice the length of the shortest side, and the third side is 27 feet more than the length of the shortest side. Find the dimensions if the perimeter is 187 feet. a=shortest side, b=second side, c=third side

A=60, B=80, and C=67

Step by step explanation:

B= 2a

C= a+27

With the information, you get the equation:

A+A+27+2A=187

Then, you have to simplify.

You then get 4a+27=187.

Now, you subtract 27 from both sides to get: 4a=60.

Divide both sides by 4 to get A= 60.

If A=60, 2A=80, so B=80. A+27=67, so C=67.

You check this by adding them up to see if they equal to 187, which in fact, they do.

A=60, B=80, and C=67.

Hope this helped!
