Question

the area of a rhombus 148.8 cm square if one of its diagonal is 19.2 find the length of other diagonal

Answer 1

Area of rhombus = 148.8 sq cm

Area of rhombus = 1/2 x d₁ x d₂

148.8 = 1/2 x 19.2 x d₂
9.6 d₂ = 148.8
d₂ = 148.8/9.6 = 15.5 cm

Answer 2

from given problem....the area of rhombus is 148.8cm²
the measure of one diagonal is 19.2cm
we know that area of rhombus is 1/2diagonal1×diagonal2
148.8=1/2×19.6×diagonal2
148.8×2/19.6=d2
d2=15.18cm
