Question

A rectangular garden 80m by 40m is divided into 4 equal parts by two cross paths 2.5m wide find area of the cross paths and area of the unshaded portion

Answer 1

80*2.5=200 m2
40*2.5=100 m2
total road area= (200+100)-(2.5*2.5)=293.75 m2

area of rectangular garden=80*40=3200 m2

so, unshaded portion's area= 3200-293.75=2906.25 m2

Answer 2

Answer: The area of cross path=$293.75\ m^2$

Now, the area of unshaded region = $2906.25\ m^2$

Step-by-step explanation:

Given: Length of rectangular garden = 80 m

Width of rectangular garden = 40 m

The width of cross path= 2.5m

The area of garden = $80*40=3200\ m^2$

The area of cross path=$(80*2.5)+(40*2.5)-(2.5*2.5)=293.75\ m^2$

Now, the area of unshaded region = $3200-293.75=2906.25\ m^2$
