Question

The area of a rectangular picture frame is 30 1/3 square inches.The length of the frame is 6 1/2 inches.Find the width of the frame

Answer 1

Area of rectangular picture frame=l×b
$let \: the \: width \: be \: x \: inhes \\ area = l \times b \\ 30 \frac{1}{3} = 6 \frac{1}{2} \times x \\ \frac{91}{3} = \frac{13x}{2} \\ x = \frac{91}{3} \times \frac{2}{13} = \frac{14}{3} = 4 \frac{2}{3} \\ the \: width \: of \: the \: frame \: is \: 4 \frac{2}{3} \: inches$
