Let second diagonal be x
Area of rhombus=1/2×d1×d2
1080=1/2×72×x
x=1080/36
x=3om
By Pythagoras theorem the side is39m
Perimeter of rhombus=4×s
=4×39
156m

area of rhombus =1080sq.m
one diagonal is 72m
let the 2nd diagonal be x
area = 1/2×product of diagonal
1080sq.m = 1/2×72× x
1089/36=x
x=30m
so, 2nd diagonal =30m
by,Pythagorean theorem
hypotenous =under root based square + height square
