Question

Q11 Find the area of a rhombus whose side is 5 cm and altitude is 2.4 cm. If
one of its diagonals is 6 cm long , find the length of other diagonal.​

Answer 1

Answer:

12cm, 4 cm

Step-by-step explanation:

area of rhombus is base ×height

base = 5cm , height = 2.4 cm

area = 5cm × 2.4cm = 12 cm

area of rhombus is 1/2 × d^1×d^2

d^1 = 6 cm

so, 1/2 × 6cm × d^2 = 12 cm

d^2 = 12/3 cm

d^2 = 4 cm

Hence, another diagonal is 4 cm
