The parallel sides of a trapezium are in the ratio 3: 5 and the height between the parallel sides is 10cm. if the bigger of the parallel sides is 30cm, find the area of the trapezium.

Step-by-step explanation:

Let

x -----> one parallel side of the trapezium

y ----> the other parallel side of the trapezium (bigger side)

we know that

The area of the trapezium is equal to

----> equation A

----> ---> equation B

we have

Find the value of x

substitute the value of y in the equation B

Find the area

substitute the values in the formula

.25
