Question

the length of a parallel side of a trapezium are in tje ratio of 4:7 if the height of trapezium is 14m and it's area is 385sq.m find the length of it's parallel side​

Answer 1

Step-by-step explanation:

Let ratio of parallel sides be 4x and 7x

h=14m

Area of trapezium=1/2×h(sum of parallel sides)

385sq.m=1/2×14(4x+7x)

385=7(11x)

385/7=11x

55/11=X

X=5m

Sides are:

4×5=20

7×5=35
