The area of a trapezium is 34 cm2 and its height is 4cm. One of the parallel sides of the trapezium is 10 cm, find the other parallel side |

Answer» p-by-step explanation:=> Area of trapeium = 34cm² => Length of parallel side=10 cm=> Height=4cm=> LET the length of other side be "X" cm=> Area = ½ (sum of parallel sides) x (distance between them)=> 34 = ½ (10 + x) (4)=> 34 = ½ x (40 + 4x)=> 34 = 20 + 2X=> 2x = 34 - 20=> 2x = 14 => x = 14/2=> x = 7 cm |
