Question

Find area of rhombus perimeter is 80cm one of whose diagonal is 24m

Answer 1

Answer:

384 sq. cm

Step-by-step explanation:

Rhombus perimeter : 4x side

.                            80 = 4 x side

'                             80/4 = side

.                              side =20 cm.

area of rhombus = diagonal x diagonal / 2  

i.e 24 x diagonal /2

if we find the second diagonal i.e. 32 by pythagoras theorem

we get area as 24 x 32 /2

i.e. 24 x 16 = 384 cm²
