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

Answer:

Area $= 30$ square centimeter

Diagonal $= 7.5$ centimeter

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 $= 0.5 * d_1 * d_2$

$d_2 = \frac{30}{0.5*8} \\d_2 = 7.5$ cm
