Question

find the area of a rhombus whose side is 7.5 cm and whose altitude is 4 cm if one of its diagonals is 8 cm long find the length of the Other diagonal​

Answer 1

Area
`= 30` square centimeter

Diagonal
`= 7.5` centimeter

Step-by-step explanation:

Area of the rhombus is equal to the product of its side and altitude

Thus,

Area of the rhombus
`= 7.5 * 4 = 30` square centimeter

Area of the rhombus is equal to half the product value of two diagonal

`30` square centimeter
`= 0.5 * d_1 * d_2\\`

`d_2 = (30)/(0.5*8) \\d_2 = 7.5` cm
