Question

parameter of 2 square formed by a wire is 20 cm and 32 if both the square are opened and why are added to form a new square find the area of a new square​

Answer 1

Answer:

Formula used:

Area of square = side × side

Calculation:

Let, perimeter of first square = 24 cm

Now 4 × one side = 24

one side = 24/4 = 6 cm

In second square perimeter = 32 cm

4 × one side = 32

One side = 32/4 = 8 cm

Now area of first square = 6 × 6 = 36 cm2

And second = 8 × 8 = 64 cm2

In question given that,

Third square area = sum of areas of first and second square

So, third area = 36 + 64 = 100 cm2

Now third area = side × side = 100 cm2

Let side = A

So A2 = 100

A = √100 = 10 cm

Now perimeter = 4 × one side = 4 × 10 = 40 cm

∴ Perimeter of third square
