Hiii. ....friends
The answer is here,
Area of shaded region = Area of square- Area of the two triangles (unshaded region)
Side of the square = 5+7=12cm.
=> Area of square = side×side.
=> 12×12 = 144sq.cm
Area of triangle =1/2× base×height.
=> 1/2 ×7×5=> 35/2.
Area of the two triangles => 2×35/2= 35sq.cm
So, Area of shaded region = 144-35
=> 109sq.cm
:-)Hope it helps u.
