A wire is bent so as to form four sides of a square. A length of 4 cm is cut from it and the remainder is again bent to form the four sides of a square. If the difference in areas of square is 25 cm^2, how long was the wire before being cut? |
|
Answer» Answer: Let X as side of the SQUARE so area of the square is x^2,total LENGTH of the wire is 4x Now 4cms is cut from 4x,remaining length is 4x-4=4(x-1)CMS length of the side is x-1)cms Original area of square is x^2 After removing 4cms area of the square formed (x-1)^2=x^2–2x+1 Given the DIFFERENCE in areas of the square is 25cm2 So x^2-x^2+2x-1=25 2x-1=25 x=(25+1)/2=13 So the length of the wire was 4*13=52cms hope it helps........................ |

Prove that 3root2 is irrational |
|
Answer» <P>Answer: Let us CONSIDER that 3root2 is a rational number. It can be written in the form p/q (p and q are co primes) p/q = 3root2 p/3q = root2 Now, p/3q = integer/interger = rational number But, this contradicts the fact that root2 is IRRATIONAL. Therefore, our ASSUMPTION that 3root2 is rational is WRONG. Hence, 3root2 is an irrational number. please please mark my answer as brainliest answer.and also follow me...✔️✔️thx.... ❤❤❤❤❤ |
