Question

the area of rohmbus is2016squarecm and its side is 65cm. find the diagonal

Answer 1

Area of Rhombus = pq/2
where p and q are the diagonals of the rhombus
so pq=2016cm²

side of a rhombus a = $\frac{ \sqrt{ p^{2} + q^{2} } }{2}$

so p²+q²=4a²=16900cm²

(p+q)²= p²+q²+2pq=16900+4032=20932cm²
So
p+q=√20932=144.67cm
