@jim_thompson5910 may you help me? please

jimthompson5910 (jim_thompson5910):

are those values the lengths of the diagonals?

jimthompson5910 (jim_thompson5910):

if so, then multiply the lengths of the diagonals and divide by 2

jimthompson5910 (jim_thompson5910):

the general formula is A = (d1 * d2)/2 where A = area of rhombus d1 = first diagonal d2 = second diagonal
