Question

the area of a trapezium is 98cm sq and the length of one of the parallel sides is 14cm and the distance between the parallel sides is 10.5 cm . find the length of the other side

Answer 1

Answer:

Step-by-step explanation:

Given :- ar( trapezium)= 98 sq cm

one parallel line = 14 cm

height = 10.5 cm

we know that

ar( trapezium )= 1/2×(sum of parallel lines)×height

98=1/2 (14 + a) 10.5

196=(14 + a) 10.5

18.6666667=14+a

a=4.6666667
