Question

a field is 120 M long and 90 M wide has to cross roads in its Centre each road is 3 M wide find the area of the remaining field

Answer 1

i have find it by seprating the field in 4 plots

Answer 2

Answer:

10179$M^2$

Step-by-step explanation:

Area of field = Length * Width = 120 * 90 Msq. =10800 Msq.

Area of the crossroad along Length of the field = 3 * 120 = 360 Msq

Area of the crossroad along Width of the field = 3 * 90 = 270 Msq.

Area of the intersection of the Two crossroads = 3*3 = 9 Msq.

Area of the remaining field = Total area of field - (Area of the crossroad along Length of the field + Area of the crossroad along Width of the field-Area of the intersection of the Two crossroads)

⇒Area of the remaining field = 10800 - (360+270-9)= 10179$M^2$
