Question

If one of the parllel sides of a trapizium shaped colony is 260m ,find the other parallel side when the area of the colony is 72000m and the distance between the parllel sides is 180 m

Answer 1

Answer:

540 m

Step-by-step explanation:

area of trapezium = 1/2 × h × (a + b)

where h is the distance between the parallel

a and b are the length of parallel

$\frac{1}{2} \times 180 \times (260 + b) = 72000\\ 90 \times (260 + b) = 72000 \\ 260 + b = \frac{72000}{90} \\ 260 + b = 800 \\ b = 800 - 260 \\ b = 540m$

therefore the length of the other parallel side is 540 m

hope you get your answer
