A rectangular Garden 18 by 40 m is divided into four eaqual paths by two cross paths 2.5 M wide.find the cost of the cross paths the unshaded portion

Answer»

The COST of the cross paths the unshaded portion:

Area 1 = 18 * 2.5 = 45

area 2' = 40 * 2.5 = 100

but there is also overlap of two paths so we have to SUBTRACT one time

so, 2.5 * 2.5 = 6.25

so TOTAL area = 45 + 100 - 6.25 = 138.75 m ^ 2
