Question

Solve this .....no. 5 and no.6

Answer 1

5.Area of rhombus = 200 cm^2
[Area = 1/2*(product of diagonals)
200= 1/2*(20*d)..d=20cm]

Now, (d/2) = a*rt2.... where a=side and d=diagonal
10 = a*rt2
a= 10/rt2
Perimeter = 4a = 40/rt2 or 20rt2 cm

6. Area of parallelogram = base* height
given height = 1/3 base or base = 3*height
108 = 3*height*height
height^2 = 108/3=36
Height = 6 cm

Answer 2
