The frame on a picture is 28 cm by 32 cm outside and is of uniform width. What is the width of the frame if 192 cm^2 of the picture shows
**
let w=width of the frame
Area of frame+picture=28*32=896
Area of frame=896-192=704=length*w=2*(28+32)*w
w=704/2*(28+32)=704/120≈5.87
width of the frame≈5.87 cm
