A building casts a 72-foot shadow on the ground when the angle of elevation of the sun is 40°. How tall is the building, to the nearest foot?

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
