Question

one parallel side of a trapezium is 10 cm less than the other.if the distance between the parallel sides is 15cm and the area of the trapezium is 600 cm square find the length of each parallel side

Answer 1

let one side =x

second side =x-10

area =1/2×(x+x-10)×15

600=1/2×(x+x-10)×15

then answer will be

45

one side is 45

second side is 35
