The length of the rectangular shape is 54 meters, and the width is 18 meters less.

The length of the rectangular shape is 54 meters, and the width is 18 meters less. How many meters of wire will it take to make a 2-row hedge around the garden?

The fence will be installed around the perimeter of the garden, therefore, it is necessary to calculate the sum of all its sides, provided that the length is 54 m, and the width is 18 m less, according to the formula:

P = 2a + 2b = 2 * 54 + 2 * (54 – 18) = 108 + 72 = 180 m – this is the length of the wire installed in 1 row.

180 * 2 = 360 m of wire will be needed in order to make a hedge around the garden in 2 rows.
