Question

the area of the trapezium with equal non parallel sides is 168 metre square if the length of the parallel sides are 3620 as shown in figure find the length of a non parallel sides​

Answer 1

Answer:

Area of a trapezium = 10metre square

Step-by-step explanation:

1/2 × (sum of 11 sides) ×height =168

∴336=(36+20)×height

∴height=336/56=6m

∴ length of non parallel side =under root 6^2 + 8^2

=under root 100

​

∴ Answer =10cm

Answer 2

Answer:

6 cm

Step-by-step explanation:

Given area of trapezium = 168cm². From the trapezium,(1/2)×(AB+CD)×BF = 168cm. Therefore,BF = 168/28 = 6cm.
