Step-by-step explanation:
Given :
In the quadrilateral ABCD,AB=BC.lf AB=6 cm,CD=7cm and DA=8cm, find the perimeter of the quadrilateral.
proof :
AB = 6 cm = BC {Given}
BC = 6cm
solving :
perimeter of the quadrilateral ABCD is
AB + BC + CD + DA = Perimeter of ABCD
substitute above values in the above equation
we get
=> AB + BC + CD + DA = Perimeter of ABCD
=> 6 + 6+ 7 + 8 = Perimeter of ABC
=> 12 + 15 = Perimeter of ABCD
=> 27 cm = Perimeter of ABCD
∴ The perimeter of the quadrilateral ABCD is 27 cm
