Question

the area of trapezium is 850 sq. cm l.one of the parallel side is 64 cm and the perpendicular distance between the parallel sides is 17 cm.Find the length of the parallel side.​

Answer 1

Answer:

Area of trapezium is 1/2×(x+64)×17. = 850 = 1/2 (x+64). =(X+64) = 1700/17 = 100 = x = 100-64 = 36cm ans.

Answer 2

GivEn:

• Area of Trapezium = 850 cm²
• 1st parallel side = 64 cm
• Perpendicular side (Height) = 17cm

To Find:

• length of other parallel side?

Formula Used:

Area of Trapezium = 1/2 × (sum of parallel sides) × Height

Step By step:

Suppose the other parallel side be x

So in:

Area = 1/2 × Sum of parallel sides × height

850 = 1/2 × (64 + x) × 17

850 × 2/17 = (64 + x)

1700/17 = 64 + x

100 = 64 + x

After substituting;

100 - 64 = x

36 = x

So,

The other parallel side is 36cm .
