Question

The area of a trapezium is 4400 sq. m. One of its parallel sides is 75 m. If the distance between the parallel sides is 80 m, find the length of the other parallel side.​

Answer 1

Answer:

35m

Step-by-step explanation:

we know that

area of trapezium = 1/2× distance between the two parallel lines( sum of two parallel lines a+b)

Given :

area of trapezium=4400sq.m

length of one parallel side =75m

distance between parallel sides=80m

Now, Area of trapezium =1/2×h(a+b)

implies. 1/2×h(a+b)=4400

1/2×80(75+b)=4400

40(75+b)=4400

(75+b)=110

b= 110 -75

implies b=35

the length of the other parallel line =35m
