Question

the area of a rhombus is 138 CM square if one of the diagonals is 11.5 cm long find the length of the Other diagonal

Answer 1

$area \: of \: rhombus \: = \frac{1}{2} \times d1 \times d2$

$138 = \frac{1}{2} \times \frac{115}{10} \times d2$

$\frac{138 \times 2 \times 10}{115} = d2$

d2 = 24

other diagonal is 24cm long
