2. Find the area of a rhombus whose one side is 13 cm and one diagonal is 24 cm.​

Answer 1

Area of rhombus = 12×d1×d2

To find the length of the diagonal AC.

△OA B, ∠AOB=90∘; OB = 12 cm; AB = 13 cm.

AO 2=AB−OB 2=132−122=25

AO =25 √= 5 cm

Therefore, length of one diagonal is 10 cm and the length of another diagonal is 24 cm.

Therefore, Area of Rhombus = 12×d1×d2=12×10×24 = 120 sq. cm.
