Ben wanted to take some money from his Friends to build his family a home. He said that he would give the money back after 12 months. So he would give 1500$ a month. How much money did he borrow?
1500*12=x
Matilda got also money, she told Ben, I got x $ from my dad and y $ from mom. all they gave me was 5000$. If I gave mom Half of the moneys I got from her than I would have 3000$ left to pay. How much did she borrow from her parents?
x+y=5000
and
x+y/2=3000
so x=5000-y
and
5000-y+y/2=3000
so
x=5000-y
and
y=4000
so x=1000 and y=4000
Answer: 1) If we talk about whole numbers then we should choose only square numbers that could be the area of square so that if we want to find its side so we a can find its square root i.e. side.
2) We can find the square root of the area of the given square to find the side length of the square.
3) No , it is not possible to find a side length that would be perfect for a square with an area of 45 square units because if we find its side we need to find its square root i.e.
................>which is irrational and √5=2.236
∴side=3×2.236=6.708 unit ......> which is not accurate we need to take approx value of it to get the side length of the square.
