The area of trapezium is 640 cm^2.If its parallel sides ate in ratio 2:3 and the perpendicular distance between the two is 16 cm,find length of each parallel side. |

Answer» -step explanation:area of TRAPEZIUM = 1/2 (sum of two PARALLEL sides) × heightlet the two parallel sides be a and bit is given that a : B = 2 : 3 => = 2x , b = 3xArea A = 1/2 (2x + 3X) × h=> 640 = 1/2 × 5x × 16=> 5x = (640 × 2) / 16=> 5x =80=> x = 16therefore a = 2x => 2×16=> 32 cm b = 3x => 3×16 => 48 m |
