Question

The ares of trapezium is 210cm2 the ratio between the length of its parallel sides is 3:4 of the hieght is 6cm find the length of both the parallel sides

Answer 1

Answer:

Step-by-step explanation:

Let the sides be 3x and 4x.

Area=1/2×(Sum of Parallel sides)×Height.

1/2×(3x+4x)×6=210

1/2×7x×6=210

42x=210×2

X=210×2/42

X=10cm

Then the length of both sides are:-

3×10=30cm

4×10=40cm.

Hence proved all.
