Problema Solution
A rectangular swimming pool is 12 meters long and 8 meters wide. A tile border of uniform width is to be built around the pool using 120 meters of tile. The tile is from a discontinued stock (so no additional materials are available) and all 120 square meters are to be used.
A) how wide should the border be? (round to the nearest tenth of a meter.)
B) If zoning laws require at least a 2-meter-wide border around the pool, can this be done with the available tile?
Answer provided by our tutors
let 'x' represent the width of the border, x>0
(12 + 2x)(8 + 2x) - 12*8 = 120
by solving we find:
x = 2.4 m

A) the border should be 2,4 meters width.
B) since 2.4 > 2 the answer is yes.
