answer :==23,27cm

Answer 1

Answer:

23 cm, 27 cm

Step-by-step explanation:

Let the length of one side be 'x' cm.

Then the other side = x + 4 cm.

Given that Area of trapezium = 475 cm² and Height = 19 cm.

Now,

∴ Area of trapezium = (1/2) * (Sum of parallel sides) * Altitude

⇒ 475 = (1/2) * (x + x + 4) * 19

⇒ 950 = (2x + 4) * 19

⇒ 2x + 4 = 50

⇒ 2x = 50 - 4

⇒ 2x = 46

⇒ x = 23 cm.

Then:

=> x + 4

=> 23 + 4

=> 27 cm

Therefore:

Length of its parallel sides are 23 cm and 27 cm.

Hope it helps!

Answer 2

Step-by-step explanation:

Area =1/2h × sum of paralles sides

= 1/2×19×(2x+4)

9.5(2x+4)=475

2x+4=50

2x=46

X=23
