Question

the diagonal of a rhombus are 24 cm and 10 cm find area and perimeter

Answer 1

Area = 1/2 * 24 * 10
         = 120 cm^2.
Perimeter s^2 = (24/2)^2 + (10/2)^2                         =  12^2 + 5^2
                       =   169
                   s = 13.
The perimeter of the rhombus = 4 * 13 = 52cm

Answer 2

The area of this rhombus= 1/2*d1*d2
= 1/2*24*10
= 12*10
= 120 cm square

Perimeters of rhombus=2√d1^2+d2^2
=2√24^2+10^2
=52cm
