Question

The area of a square is 25. Find the perimeter of the square with 4 times the area of the first square.

Answer 1

Answer:

40 Units

Explanation:

Given,

Area of square = 25sq. unit

Let this area square be called as A1 .
To find ,

Perimeter of 4*A1  [ lets call the area of new square as A2]

We know that ,

Area od square = side * side

therefore , 4*A1 = 4*25 sq. unit

                  => 4*A1=100 sq unit

                 =>A2 = 100 sq unit

                 => (Side)^2 = 100sq. unit

                 => side =$\sqrt{} 100$

                 => side = 10 unit

Using the formulae to find perimeter of square ;

Perimeter = 4*Side

                 =4*10 unit

                 =40 unit
