Answer:

\underline{\fbox{\fbox{\rm{Solution :}}}}

Solution :

(i) The diameter of a circle is twice its radius.

D = 2r

(ii) The area of a rectangle is the product of its length and breadth.

A = l × b

(iii) The selling price equals the sum of the cost price and the profit.

SP = CP + profit

(iv) The total amount equals the sum of the principal and the interest.

A = P + I

(v) The perimeter of a rectangle is two times the sum of its length and breadth.

Perimeter = 2(l + b)

(vi) The perimeter of a square is four times it side.

Perimeter = 4l

Where,

D = Diameter

r = radius

A = Area

l (small letter 'L') = length

b = breadth

SP = Selling Price

CP = Cost Price

A = Amount

P = Principal

I (capital letter 'i') = Interest
