A field is 1
3
km long and 1
4
km wide. It is proposed to sow wheat in 3
4
part of the field and
grow vegetables in the remaining part. Find the area of the field in which vegetables are to be
grown.

Answer 1

Given : A field is 1/3 km long and 1/4 km wide

It is proposed to sow wheat in (3/4) part of the field and grow vegetables in the remaining part.

To Find :  area of the field in which vegetables are to be grown.

Solution:

A field is 1/3 km long and 1/4 km wide

Area of field = (1/3)(1/4)  = 1/12  km²

proposed to sow wheat in (3/4) part of the field

grow vegetables in the remaining part. = 1 - 3/4

= 1/4

area of the field in which vegetables are to be grown. = (1/4)(1/12)

= 1/48   km²

1/48   km² is the   area of the field in which vegetables are to be grown.

Answer 2

HELLO DEAR,

GIVEN:- A field is 1/3 km long

And 1/4 km wide.

It is proposed to sow wheat in 3/4 part of the field.

And grow vegetables in the remaining part.

TO FIND :- The area of the field in which vegetables are to be

grown.

SOLUTION:- To convert the given lenght and width into m.

1 km = 1000m

Lenght of field is 1/3 km.

So, 1/3km = 1000/3 m

= 333.3 m

Width if field is 1/4 km.

So, 1/4 km = 1000/4 m

= 250 m.

Total area of field = ( lenght × width)

= (333.3 × 250)

= 83325 m².

And the field in which vegetables are grown = ( total field - field in which wheat are sow)

= {(83325) - ( 83325× 3/4 ) }

= {(83325) - ( 62493.75)}

= 20831.25 m²

1 m = 1/1000 km

1 m² = (1/1000000) km²

20831.25 m² =( 20831.25/ 1000000) km²

= 0.02083125 km²

= 1/48 km²

I HOPE IT'S HELP YOU DEAR,

THANKS.
