Answer 1

Answer:

D

Solution :

(i) Let a side of the square be 10 units. <br> (ii) Let the side of square PQRS be 10 cm, then side of square ABCD is 12 cm. <br> (iii) Find the areas of PQRS and ABCD and find the required percentage.

Answer 2

Answer:

44%

Step-by-step explanation:

area of square = side*side

let x be the side of a square

area of square pqrs = x*x = x square

area of square abcd = 1.2x * 1.2x = 1.44x square

so,

(1.44x - 1.0x /1.0x) * 100

=>(0.44x/1.0x) * 100

=>abcd square is 44% more than square pqrs
