Answer:
18 cm
Step-by-step explanation:
From the question above,
Area of a rhombus
A = d₁d₂/2.................. Equation 1
Where A = area of the rhombus, d₁ = length of one diagonal, d₂ = length of the other diagonal
make d₂ the subject of the equation
d₂ = 2A/d₁............... equation 2
Given: A = 72 cm², d₁ = 8 cm
Substitute these values into equation 2
d₂ = (2×72)/8
d₂ = 144/8
d₂ = 18 cm.
