Question

The frame around a picture with an area of 192 square inches, measures x inches across. The length of the picture with its frame is 40 inches and the width of the picture with its frame is 24. What are the dimensions of the picture?

Answer 1

Okay so
area of picture= 192cm
area of frame= 40×24=960

960÷ 192= 5

Therefore the picture is 1/5 of the frame.
Length of picture = 1/5 × 40 = 8cm
Width of picture = 192/8 = 24

The dimensions of the picture are then 8cm × 24 cm.
