Question

the area of a Trapezium is 0.05 metre square and its height is 20 CM if one of the parallel side is longer than the other by 8 cm find the length of longest parallel side​

Answer 1

Answer:

$\frac{1}{2}(x + y)h$

is area for trapezoid

$\frac{1}{2} (x +x + 8) \times 20$

equals 500 cm ²

$\frac{2(x + 4)}{2} \times 20 = 500$

$x + 4 = \frac{500}{20}$

$x + 4 = 25$

$x = 21$

Answer 2

Answer:

the area of trapezium =1/2*(a+b)*height .

according to question.

given. 0.05m square , height =20cm and one parallel side is 8cm

given in metre change in centimetre.

now.

0.05*/1000=1/2*20*2x+8

50=2x+8

2x=42

x=21

given one parallel side=8cm

second parallel side =x+8cm

21cm+8cm=29cm

so answer is 29cm.
