Question

find perimeter of a square it its diagonal is 10√2​

Answer 1

Answer :

• Perimeter of square is 40 units

Given :

• Diagonal is 10√2

To find :

• Perimeter of a square

Solution :

To find the perimeter of square we need to find the side of square then after we have to find the period of square

Given

• Diagonal = 10√2

》Side of square = 10√2/√2

》Side of square = 10

Side of square = 10

Finding the perimeter of square :

We know that

• Perimeter of square = 4a

Where , a = 10

》Perimeter of square = 4a

》Perimeter of square = 4 × 10

》Perimeter of square = 40 units

Hence , Perimeter of square is 40 units

More Explanation :

• A square has four sides
• A square has four vertices
• Area of square = (a)²
• Perimeter of square = 4 × a
• Where, a is side of square
• Opposite sides of the square are parallel
• The diagonal of the square divide it into 2 similar isosceles triangles
• All four sides of a square are congruent or equal
