Given:
- ABCD is a square having area 64cm²
Find:
- Area of square formed by joining the mid-points.
Solution:
F1stly Let a is the length of the side of Square
So, we know that
where,
- Area of square = 64cm²
So,
________________________
Here, EFGH area the mid points of sides of square
Then, AH = 8/2 = 4cm = AG
In AGH
By Pythogoras Theorem
where,
- AG = 4cm
- AH = 4cm
So,
So, GH = 4√2cm
Again using
where,
- Side, a = 4√2cm
So,
Hence, Area of Square EFGH = 32cm²
