Question

the area of a rhombus is 120 sq. cm. if one diagonal is 20 cm, find the other diagonal

Answer 1

area of rhombus=1/2×d1×d2
120=1/2×20×d2
120=10×d2
120÷10=d2
12cm=d2

Answer 2

hi frnd

in rhombus area formula is ,,,, 1/2 × d1 × d2

so ,,, here d1 = 20cm
and let d2 to be X

1/2 × 20 × X = 120

10 × X = 120

X = 120/10

X = 12cm

d2 = X = other diagonal = 12 cm
