Answer 1

Step-by-step explanation:

Let one side of trapezium is x, then other side parallel to it = 2x 

Area of trapezium = 165 cm²

Height of trapezium = 10 cm

Now, area of trapezium = 1/2 (p₁ + p₂) × h

⇒ 165 = 1/2(x₁ + 2x) × 10 

⇒ 165 = 3x × 5 

⇒ 165 = 15x

⇒ x = 165/15 

⇒ x = 11

Therefore, 2x = 2 × 11 = 22

Therefore, the two parallel sides are of length 11 cm and 22 cm. 

Answer 2

Answer:

one parallel side be 11cm

the other parallel side be 22cm

Step-by-step explanation:

let one of the parallel side be x

then the other parallel side be 2x

area of trapezium = 1/2×sum of parallel sides× height

165cm^2 = 1/2×(x+2x)×10(cm)

165 = 1/2 × 3x × 10

165 = 15x

11 = x

putting the value of x in

x= 11

2x=22
