Question

area of trapezium is to 80 metre square one of its parallel side is 18 meter its height is half of the Other parallel side find the length of the Other parallel side and height of the trapezium​

Answer 1

Step-by-step explanation:

let the other side of Trapezium= x

and height = half of other side means x/2

area of Trapezium= 1/2 X height ( sum of parallel sides)

80= 1/2 X x/2 X (x +18)

80= x/4 (x+18)

320 = x( x +18)

= x² +18x -320

now you can find the solution ... you factories this and you get value of x
