Question

The area of a trapezium is 34cm square and the length of one of the parallel sides is 10cm and it's height is 4cm. find the length of other parallel side?

​

Answer 1

Answer:

the length of other parallel side = 7 cm

Step-by-step explanation:

Area of trapezium=  (a+b )/2 * h

34 = (10 + b)/2 * 4

34 = (10+ b) *2

34 = 20 + 2b

14 = 2b

b = 7 cm

Answer 2

Answer:

given,

area=34cm

length of one parallel side=10cm

area=1/2X(a+b)h

=1/2X(10+b)4

34=2(10+b).

(1/2and4 get cancel)

34=20+2b

34-20=2b

14=2b

14/2=b

7cm=b

length of other parallel side is 7cm
