The perimeter of an isosceles trapezoid is 110 m and the bases are 40 m and 30 m in length. Calculatelength of the non-parallel sides of the trapezoid and its area. |

Answer» Let non parallel sides be x40 m +30m+x+x = 1102x = 110- 70x = 40/2=20mdraw a perpendicular from any upper point by using pythagoras(10)²+ (height)²= (20)²100+(height)²= 200height= √100 = 10= area = 1/2(a+b)* h= 1/2(30 + 40)*10= 1/2*70*10= 350m² |
