The formula for calculating the area of a rhombus is expressed as
Area = d1d2/2
where
d1 is the length of one diagonal
d2 is the length of the other diagonal
From the information given,
length of one diagonal = 12 + 12 = 24
length of other diagonal = 9 + 9 = 18
By substituting these values into the formula,
Area = 1/2 x 24 x 18
Area = 216 in^2
