Sorry diagonal of a rectangle is l^2 b^2

Ans 4:

Class : Class 7
please provide explanation soon

Class : Class 7
it is very simple and can be solved with Pythagoras.Length=2y Breadth=yroot of [(2y)square ysquare]=9 x root of 5root of [4ysquare ysquare]=9 x root of 5root of 5ysquare=9 x root of 5 = y x root of 5thus y = 9 and 2y = 18p=54

Ans 6:

First of all,diagonal of a rectanhle=square root of l^2 b^2,so 9×square root of 5 is square root of 81 × 5 that is 405 so here 2x is l and x is b.if i m taking l is 18 and b is 9 and squaring them we get 405 so perimeter of the rectangle is 2(18 9) that is 54.

w=xl=2xd=9root52(l b)=?2(x 2x)=?using pythogras theorem,xsquare 4 x square=(9root5)squared5xsquare=405x square=81x=9hence substitute values with x,perimeter=54

Ans 10:

Class : Class 8
This can be solved like this: take length as 2x and breadth as x. Applying the pythagoras theorem, (x)^2 (2x)^2 = (9 * root 5)^2. Equal to x squared 4x squared = 9 squared * root 5 squared 5x squared = 81 * 5. 5 and 5 cancel on both sides. x squared = 81 x = 9 = breadth 2x = 18 = length perimeter = 2 (l b) 2 * 27 = 54

the answer should be equilateralbecause we have studied everywhere that two equilateral triangle(with same length) are kept such as there one side of both the triangle are adjacent , is a square

Yes the correct answer is π because 22/7 is of the form p/q and if we use π the its value will be 3.14 appox it doesn't have proper value by this we can say that 22/7 is rational number and π is an irrational number

Ans 2:

Class : Class 10
Only Π is irrational because 22/7 is a fraction in p/q form.
