pls find the answer ,i am not able to get it​

Answer 1

Answer:

area of ABCD = 100cm ² and

area of EFGH = 125/2 = 62.5 cm²

Step-by-step explanation:

area of ABCD = a² = (10)² = 100 cm²

Area Of EFGH = Area of ABCD - ( Area of EDH + Area of AEF + Area of BGF )

Also area of EDH = 1/2 ( base *height)

= 1/2(5*5) = 25/2

And same for Area of AEF and Area of BGF.

So Area of EFGH = 100 - [ 25/2+25/2+25/2 ]

Area of EFGH = 100-75/2 = (200 - 75 ) / 2

Area of EFGH = 125/2 = 62.5 cm² (answer)
