Answer:
A = 42 cm^2
Step-by-step explanation:
To find the area of a rectangle , multiply the length and the width
A = lw
A = 7cm * 6 cm
A = 42 cm^2

Consider first two digits and then the next two digits.If there are three digits in the given number then first consider the first digit and then the take two digits together
6 | 4489 | 6x
36
12x | 889 |
Now the number 889 has 9 in units place so take a share number which has 9 at the end (ex.3*3=9 and 7*7=49)
So put 7 in the place of x and multiply the x value with 12x(that is 127) u will get the remainder as 0
Therefore the square root of 4489 is 6x*6x i.e. 67*67=4489
Answer:
24
Step-by-step explanation:
We have a system of equations, so we can start with the second equation:
![x-y=2](https://tex.z-dn.net/?f=x-y%3D2)
And move y to the other side to isolate x:
![x=2+y](https://tex.z-dn.net/?f=x%3D2%2By)
Now we can replace x into the first equation:
![(2+y)^{2} -y^{2} =48\\ (2+y)(2+y)-y^{2} =48\\ 4+4y+y^{2} -y^{2} =48](https://tex.z-dn.net/?f=%282%2By%29%5E%7B2%7D%20-y%5E%7B2%7D%20%3D48%5C%5C%20%282%2By%29%282%2By%29-y%5E%7B2%7D%20%3D48%5C%5C%204%2B4y%2By%5E%7B2%7D%20-y%5E%7B2%7D%20%3D48)
Notice that we can cancel out the y squared terms:
![4+4y=48\\ 4y=44\\ y=11](https://tex.z-dn.net/?f=4%2B4y%3D48%5C%5C%204y%3D44%5C%5C%20y%3D11)
Now we just need to find x by replacing y into the second equation:
![x-11=2\\ x=13](https://tex.z-dn.net/?f=x-11%3D2%5C%5C%20x%3D13)
And finally, add them:
![x+y=11+13\\ x+y=24](https://tex.z-dn.net/?f=x%2By%3D11%2B13%5C%5C%20x%2By%3D24)
Hope this helps.
