Problema Solution
The area of a rhombus is 120 sq m. if one diagonal is 20 cm, find the other diagonal.
Answer provided by our tutors
let
d1 = 20 cm = 20/100 m = 0.2 m one diagonal
d2 = the other diagonal
A = 120 m^2
the are of the rhombus is A = (1/2)*d1*d2 thus
(1/2)*d1*d2 = 120
plug d2 = 0.2 m into the last equation
(1/2)*0.2*d2 = 120
by solving we find
d2 = 1200 m
