HENCE : 120 degree will be formed .
HOPED IT HELPED
a ( s a ) = length x width = 3 x * 5 = 15 x
the area of the sitting area and the border together:
a ( s a + b ) = ( 3 x + 6 ) * 11 = 33 x + 66
the area of the flower border:
33 x + 66 - 15 x = 18 x + 66 = 6 ( 3 x + 11 ) - in factored form.
answer: 6 ( 3 x + 11 )
