Question

the of the trapezium this 300 metre square and the ratio of the parallel side is 2 ratio 3 if the altitude is 15 cm find the length of the parallel side

Answer 1

Answer:

please mark me as a brianlist

Step-by-step explanation:

Area of trapezium is given by

A=

2

1

(a+b)h

If one side is a then the other side is a−16 since the difference of parallel sides is 16

∴ A =

2

1

(a+a−16)×15=300

⇒

2

1

(2a−16)×15=300

⇒(2a−16)×15=600

⇒(2a−16)=40 [By dividing both side by 15]

2a=56

a=28 m

The other parallel side=a−16

a−16=28−16=12

Therefore, the sides are 28m and 12m.
