Question

A landscape architect has designed a planter surrounding two birch trees, as shown. The planter is to be outlined with redwood edging in the shape of a rectangle and two squares. If the material costs 13¢ a running foot, how much will the redwood cost for this project?
$ Your answer was incorrect, but has changed from what was graded.

Answer 1

total wood required is for the two squares and one rectangle
wood for one square = 5 ft x 4 sides = 20 ft
so wood required for two such squares = 2 x 20 ft = 40 ft
wood required for rectangle is (10+20+10+20) ft = 60 ft

so total 40 + 60 = 100 ft wood required

cost of one foot is 13 cents
so cost for 100 ft is 13x100 =1300 cents = 1300/100 dollar = 13 dollar

Answer 2

so the answer is 13 dollars
