Question

A garden is rectangular with a width of 5 feet and a length of 6 feet. If it is surrounded by a walkway 3 feet wide, how many square feet of area does the walkway cover?

Area of the walkway =  ft2

Answer 1

garden = 5(6) = 30 ft^2

walkway + garden area = (5+2(3))(6+2(3)) = (5+6)(6+6) = 11(12) = 132

walkway area = total area minus garden area = 132 -30 = 102 ft^2
