Question

The area of an isosceles trapezium is 168 sq metres. if the lenghth of the parallel sides are 36cm and 20cm respectively,find the lengths of the non-parallel sides​

Answer 1

Answer:10 cm

Step-by-step explanation:

Area of trapezium=1/2*height(a+b)

1/2*h(36+20)=168cm^2

1/2*h(56)=28

28h=168

H=6

Pythagoras theorem=h^2=p^2+b^2

H^2=36+64

√100=10

Length of non parallel sides=10 m
