Question

lenhth of a rectangular field is 3\2 times its breadth if length of the field be 63 metres, find the area of the rectangular field. if a path 1•5 metres wide runs round it. find the area of the path​

Answer 1

Area of the path will be 324m²

Step-by-step explanation:

3x/2=63m

x= 63*2/3

x= 21*2

x= 42m

Therefore the breadth will be 42m

Now the area of the inner rectangle would be:

length×breadth

= 63m×42m

= 2646 m²

New length= (63+1.5+1.5)m

= 66m

New breadth= (42+1.5+1.5)m

= 45m

Now the area of the outer rectangle would be:

length×breadth

= 66m×45m

= 2970 m²

Therefore, the area of the path will be:

Area of outer rectangle- Area of inner rectangle

= 2970m²- 2646m²

= 324m²

Hope this helps...
