Rafeeq bought a field in the form of a quadrilateral (ABCD)whose sides taken in order are respectively equal to 192m, 576m,228m, and 480m and has a diagonal equal to 672m. a. Find its area to nearest square metre.
 b. The cost of 1 meter square land is equal to 200AED, how much did he spend to buy the field.
c. The cost of fencing 1m is equal to 12.50AED, how much did he spend to fence the field.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
