Question

a rectangle Stone in a piece of costume jewelry has a width of 4/5 inch and an area of 7/10 square inch. is a silver wire with a length of 3 1/2 in long enough to outline the stone? explain how you solve this problem.

Answer 1

First, we must find the length and width of the stone.  To do this, divide the area by the side that we know.  7/10*5/4  This comes to 7/8, the other side length.  Adding 7/8 and 5/4 together and multiplying by two gives us the perimeter.  This comes out to 17/4, or 4 and 1/4 inches.  Therefore, 3.5 inches of wiring would not be enough.  Please mark Brainliest!!!
