Question

the area of a rectangal is 225cm and its one side is 25cm find its other side

Answer 1

Answer:

The Breadth of the rectangle is 9 cm.

Step-by-step explanation:

Given :

Area of the rectangle = 225 cm

One side = 25 cm

To find :

The other side

Solution :

Let the other side be as y

★ Area = $\boxed{\sf{Length \times Breadth}}$

⇒ 225 = y × 25

⇒ 225 = 25y

⇒ y = $\tt{\dfrac{225}{25}}$

⇒ y = 9

Breadth = 9 cm

$\therefore$ The Breadth of the rectangle is 9 cm.

$\rule{300}{1.5}$

Verification :

As the Breadth is 9 cm, check whether the area is 225 cm² or not.

⇒ 225 = 9 × 25

⇒ 225 = 225

⇒ LHS = RHS

$\therefore$ The Breadth of the rectangle is 9 cm.

Answer 2

$\large \underline{ \underline{ \sf \: Solution : \: \: \: }}$

Given ,

$\star$Area of rectangle = 225 cm

$\star$Length of rectangle = 25 cm

We know that ,

$\large \fbox{ \fbox{ \sf \: Area \: of \: rectangle = Length × Breadth </p><p> \: }}$

$\to \sf 225 = 25 × Breadth \\ \\ \sf \to</p><p>Breadth = \frac{225}{25} \\ \\ \sf \to</p><p>Breadth = 9 \: \: cm</p><p>$

Hence , the required value is 9 cm
