(x) 1P= ……Rs​

Answer 1

(i) 1m = $\sf{\dfrac{1}{1000}}$km

(ii) M increased by thrice N = M + 3N

(iii) a,b,c and d are in proportion when…?

a × d = b × c

(iv) Perimeter of square = 4 × side

(v) Perimeter of equilateral triangle = 3 × side

(vi) Perimeter of pentagon= 5 × side

(vii) Area of rectangle = length × breadth

(viii) Area of square= side²

(ix) 1000 mg = 10 g

(x) 1P= $\sf{\dfrac{1}{100}}$Rs
