Aframe around a rectangular family portrait has a perimeter of 60 inches. the length is 15 inches less than 2 times the width. find the length and width of the frame

Step-by-step explanation:

Let x be the width of the  rectangular family portrait  , then its length will be 2x-15.

Formula to find perimeter :-

   (1)

Since, the perimeter of the frame = 60 inches, then substitute P=60 in (1), we get

Add 30 both sides , we get

Divide 6 on both sides , we get

hence, Width = 15 inches

Length = 2(15)-15=15 inches.

Hence, the  length and width of the frame are 15 inches by 15 inches.
