Question

find the answer in the following ​

Answer 1

Answer:

The correct answer is.

i) x - y = 10

ii) x^2 - y^2 = 400

iii) The value of x + y is 40

iv) length of the sides of big square is 25cm and

length of the sides of small square is 15cm

Answer 2

Step-by-step explanation:

Area of the largest square = 400 cm²

Side of the square = 400÷4 = 100cm

smaller square's side =y

y= x - 10

x= 100 so ,

y =100- 10=90cm

Answer 1 : x - y = 100 - 90 = 10

Answer 2: x²-y²= 100²-90²=10000-8100=1900

Answer 3: x+y= 190

Answer 4: larger square's side =100cm

smaller square's side =90cm
