Question

the perimeter of a rhombus is 20 cm and one of its diagonals main measures 8 centimetre find the other diagonal and area of the Rhombus​

Answer 1

Given perime

ter of rhombus =20cm

one diagonal (d1)=8cm

perimeter of rhombus =20cm

4a =20

a=5 cm

d1=8cm /2

d1 =4cm

by Pythagoras

(h)^2 = (b)^2 +(p)^2

25-16 =(p)^2

square root of 9 = p

p= 3cm

d2 = 6cm

area = 1/2 × d1×d2

= 1/2 × 8×6

24cm^2
