Question

a rectangular field 750m long and 450 m broad has two roads in the middle of it ,which are 5m wide , running at right angles to each other .one is along the length and the ofher along the breadth. find the area of the road.

Answer 1

length of field = 750
breadth of field = 450
width of road = 5
area of length running along road (x)= 750*5=3750
area of breadth running along road (y)= 450*5=2250
 area of path = x+y-crosing area over field
                  = 3750+2250-5^2
                =6000-25
                 = 5975m^2

Answer 2

Answer:

length = 750

breadth = 450

width = 5

area of length running along road = 750×5=3750

area of breadth running along road = 450×5=2250

area of road = 3750+2250-5×5

6000-25

5975m2
