Question

The length of a rectangular board is 10 cm longer than its width. The width of the board is 26 cm. The board is cut into 9 equal pieces. If the area of each piece is 104 cm, what are the dimensions of each piece?

Answer 1

Each piece will be 26cm by 4cm.

Width is 26 cm.
Length is 36 cm. The problem states that the length is 10 cm longer than the width. Since width is 26 I just added 10 to arrive at 36 cm.

36 / 9 = 4 cm.

The width will still be 26 but the length is now 4 cm. 

Area = length * width
Area = 4 * 26
Area = 104 cm
