Question

The area of a trapezium is 1920 cm2. if the height is 30 meters and one of the parallel side is 40 meters find the other parallel side

Answer 1

Answer:

The length of other parallel side is 124 cm

Step-by-step explanation:

Area of Trapezium= 1/2× sum of parallel side× hieght

Let the length of other parallel side be x cm

A/q

1/2×(40+x) × 30= 1920

1/2× 120+30x = 1920

15x = 1920-60

x= 1860/15

x= 124

Hence ,length of othe parallel side will be 124 cm
