Answer 1

Answer:

mark me as the brainliest

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:

Given :-

☄Area = 165 cm² .

☄height = 10 cm .

☄parallel sides = x and 2x .

To find :-

⚠️ value of Parallel sides !

Answer :-

$area \: of \: trapezium = \frac{1}{2} \times (sum \: of \: parallel \: sides \: ) \times height$

$165 = \frac{1}{2} (x + 3x) \times 10$

$165 = \frac{1}{2} \times 3x \times 10$

$165 = 15x$

$x = 11 \: .$

therefore ,

parallel sides are :-

• ✅ x = 11 cm ✅

• ✅ 2x = 22 cm ✅
