Question

Perimeter of rhombus is 60 cm and of its diagonal is 24 cm

Answer 1

Hey!

♣ QUADRILATERALS ♣

Given.
Perimeter = 60 cm
4a = 60
a = 60/4 = 15 cm
So, Side = 15 cm

We know,
Pythagorean Theorem,
H² = B² + P²
(AB)² =  (OA)² + (OB)²
(15)² = (OA)² + (12)²
225 = (OA)² + 144
225 - 144 = (OA)²
81 = (OA)²
9 = OA
Then AC = 2 x 9 = 18 cm

Now, Area = 1/2 * product of its diagonals
                 = 1/2 * 24 * 18
                 = 216 cm² 

Answer 2

Answer:

answer is 18 by using Pythagoras
