AB- 3in.
BC- 5in.
CD- 7.2in.
sorry i don't really have an explanation I just looked at the picture and i guess imagined it in my head? lol sorry but here are the answers I hope that helps at least a little bit :))
Use the way that kids use i.e trial and error method .
Solution:-
The set given by

Lets understand
- See the first term any natural value will make it natural .
Come to 2nd one.
- n should be a multiple of 8 to make it whole.
Come to third one
- n should be a number which makes the sum a perfect square by which we get a natural no.We have to solve it w.r.t to 2nd one
Lets think
Nearest squares to 225 are 196 and 289
We can't take 196 as we have to take a positive one other wise it will come in terms of i.
Take 289


Its divisible by 8 .
Rewrite the set



Hence n=64
You need 96 Square yards of carpet
2(5.9) is 11.8
Hopefully i is right I did this in my head.
