The diagram shows the width and height of a table. Mr. Howell wants to build a table with the same ratio of width and height as
just olya [345]

Based on the diagram and the ratio of width and height in it, the width that Mr. Howell should make his table is 48 inches .

<h3>How wide should Mr. Howell's table be?</h3>

The width of the table in the diagram is 12 cm and the height is 6cm.

This means that the ratio of width to height is:

12 : 6

2 : 1

As Mr. Howell wants his table to be 24 inches high, the width of the table would be:

2 : 1

x  : 24

Cross-multiply to get:

x = 48 inches
