A rectangle and a paralleologram of equal area and equal base are given.if p and r denote their respective perimeters,the relation between r and p is 1)r>p2)r

​

​

​

Let the base is a and other site of rectangle is b then area of rectangle is ab and let other site of parallogram is C and acute angle is θ then area of llgm in term of two triangle is 2(1/2)acsinθ. And as given ab = acsinθ and then sinθ = b/c
