Question 1060374
Let t be the thickness of the frame. Then:
(20-2w)(14-2w)=184
280-68w+4w²=184
4w²-68w+96=0
w²-17w+24=0
Using the quadratic formula, we get two roots of 15.4462219947 and 1.55377800528. The most sensical answer is the smaller root, giving us a frame of width 1.55377800528 inches. &#9786;&#9786;&#9786;&#9786;
