Question

Lengths of the parallel sides of a trapezium are 8.7 cm and 5.3 cm. If area of trapezium is 31.5 sq cm, then it's height is equal to​

Answer 1

Answer:

height is 1.37 m

Step-by-step explanation:

we know, area of the trapezium = hab/2

ATQ, hab/2 = 31.5

or, h×8.7×5.3= 63

or, h= 63/ 46.11 = 1.37 m

Answer 2

answer:→4.5

→4.5

step-by-step:

area of trapezium=1/2×(sum of parallel sides)×hieght

31.5 = 1/2×(8.7+5.3)×h

31.5 =1/2×14×h

31.5 =1×7×h

31.5 =7×h

31.5/7 = H

4.5 cm =Hieght
