Answer :

68-centimeter-long rope is used to make a rhombus

The above statement states that perimeter of the rhombus is 68 cm.

And they have given that diagonal (d_{1}) is 16 cm

(In question they have given that as meter that should be a meter)

Perimeter = 4 × a

Where,

a = side of the rhombus.

68 = 4a

a = 17 cm

From the triangle AOD

AD^{2} = AO^{2} + OD^{2}

17^{2} = 8^{2} + X^{2}

X = √(289-64)

= 15

(i) The distance between the other two corners (d_{2}) = 2X

= 2 × 15

= 30 cm

(ii)The area of the rhombus = × ×

= × ×

= 60 cm^{2}
