Question

Given the area, find the length of the side of the following squares:

a)Area of square = 625sq cm

b)Area of squarc=900 sq.cm

Answer 1

Answer:25/120cm

Hope this helped you .

Step-by-step explanation:

A//        A square has equal length on all its sides, so the area of square is

Length x Length = 625

Which is

Length ^2 = 625

We want the number that when it times it’s self it’s 625

It can be done by square root of 625 which is 25. So the length of side is 25.

Or look at the prime factorization of 625 ( or just factors) and what number they can make up

Which is 5x5x5x5 = 625

They can make up

5^2 x 5^2 = 25 x 25 that is the “same” number

So the length is 25.

B/ Area of the square (side x side) = 900 sq.cm

Therefore, the side of the square = Root of (900) = 30 cm.

Hence ,the perimeter = 4 x side = 4 x 30 = 120 cm.

Answer 2

Answer:

• If the area of the square is 625 sq. cm then the side is 25 cm.
• If the area of the square is 900 sq. cm then the side is 30  cm.

Step-by-step explanation:

Given:

a)Area of square = 625sq cm

b)Area of square=900 sq.cm

Find: Side of the square

Formula :

Area of square  = side × side

a) If  area of square = 625sq cm

side × side  = 625

$side = \sqrt{625}$

side = 25 cm

So, if the area of square = 625 sq. cm then the side is 25 cm.

b)Area of square=900 sq.cm

side × side  = 900

$side = \sqrt{900}$

side = 30 cm

So, if the area of square = 900 sq. cm then the side is 30  cm.
