Question

The side of rectangular piece of paper are in the ratio 2:3 . If the area is 150 , find the length of it's side

Answer 1

Answer:

10

Step-by-step explanation:

Let the sides be 2x and 3x

So,

Area of rectangle = length × breadth

150 = 2x × 3x

150. = 6x sq.

150 / 6. =. x sq

25. =. x sq

Root 25. = x

5. = x

So,

Length = 2x = 2×5 = 10

➡️ 10

Answer 2

Answer:

The length - 10cm.

The Breadth - 15 cm.

Step-by-step explanation:

Given -

The side of rectangular piece of paper are in the ratio 2:3

The area is 150.

To Find -

The length of Sides.

Solution -

Consider the -

Sides as - 2x & 3x.

Now,

As we know,

Area - L × B.

So,

⇒ 150 = 2x × 3x

⇒ 150 = 6x

⇒ x² = $\sf \dfrac{150}{6}$

⇒ x² = 25

⇒ x = √25.

⇒ x = 5

Now,

Length - 2 × 5 = 10 cm.

Breadth - 3 × 5 = 15 cm.
