Question

each side of a rhombus is 61cm and one of its daigonal is 22 cm long.find the the length of the other daigonal and the area of the rhombus

Answer 1

Answer:

Step-by-step explanation:

half diagonals and a side makes a right triangle so we use pythagoras theorem.

(I)

x^2 + 11^2 = 61^2

x^2 + 121 = 3721

x^2 = 3600

x = 60

The length of the other diagonal is 120.

(ii)

Area = 1/2 d1xd2

= 1/2 (22)(120)

=1320.
