A house is 24 m by 9 m

Question

A house

24

m by

9

m is surrounded by a walkway

1.7

m wide.

​a) Find the area of the region covered by the house and the walkway.

​b) Find the area of the walkway.

Answer 1

(24 +2(1.7)) x (9+2(1.7)) = area of the house and walkway

= 27.4(12.4) = 339.76 ft^2

the walkway alone = total area minus house area = 339.76-9(24) = 339.76 - 216

= 123.76 ft^2

house alone = 9(24) = 216 ft^2
