Question

The area of the trapezium shaped field is 360 sq.m. The distance between the two parallel sides is 10m and one parallel side measures 20m. Find the other parallel side.

please answer me I will mark you as brain list​

Answer 1

Answer:

Given,

Given,Area of trapezium =360m2

Given,Area of trapezium =360m2Distance between two parallel lines =20m

Given,Area of trapezium =360m2Distance between two parallel lines =20mOne parallel side =25m

Given,Area of trapezium =360m2Distance between two parallel lines =20mOne parallel side =25m 

Given,Area of trapezium =360m2Distance between two parallel lines =20mOne parallel side =25m Let's assume the second parallel side to be x m

Given,Area of trapezium =360m2Distance between two parallel lines =20mOne parallel side =25m Let's assume the second parallel side to be x m∴  Area =(25+x)×20

Given,Area of trapezium =360m2Distance between two parallel lines =20mOne parallel side =25m Let's assume the second parallel side to be x m∴  Area =(25+x)×20⇒360=(25+x)×20

Given,Area of trapezium =360m2Distance between two parallel lines =20mOne parallel side =25m Let's assume the second parallel side to be x m∴  Area =(25+x)×20⇒360=(25+x)×20⇒x=36−25=11m

Given,Area of trapezium =360m2Distance between two parallel lines =20mOne parallel side =25m Let's assume the second parallel side to be x m∴  Area =(25+x)×20⇒360=(25+x)×20⇒x=36−25=11mTherefore, the second parallel side is 11m
