Question

if the area of a rombus is 400cm2 and one diagonals length is 40cm , then find the measurement of its author diagonal

Answer 1

Answer: the measurement of its other diagonal = 20 cm

Step-by-step explanation:

see

area of rhombus is also

(d₁ * d₂) / 2

area = 400 cm₂

d₁ = 40 cm

so

=> 40 * d₂ / 2 = 400 cm²

=>20 * d₂ = 400

=> d₂ = 400/20

=> d₂ = 20
