Question

the perimeter of a rectangle is 25 metre and one of its side is 5 metre how many metre is other side​

Answer 1

Answer:

the other side of the rectangle is 7.5 m

Step-by-step explanation:

Given :

Perimeter = 25 m

One side = 5 m

To Find :

The second side

Solution :

A rectangle is a quadrilateral with two pairs of parallel lines.

The opposite sides of a rectangle are equal.

Each angle of a rectangle is a right angle.

Let the other side be y.

★ Perimeter = 2(Length + Breadth)

⇒ 2(5 + y) = 25

⇒ 10 + 2y = 25

⇒ 2y = 25 - 10

⇒ 2y = 15

⇒ y = 15/2

⇒ y = 7.5

Other side = 7.5 m

Therefore, the other side of the rectangle is 7.5 m

Answer 2

AnswEr:-

The other side of rectangle = 7.5 m

Given :-

• Perimeter of rectangle = 25 m
• One side = 5 m

To find :-

• Other side of rectangle = ?

We know,

☛ Perimeter of rectangle = 2(l + b)

• Plugging values:-

⇒ 25 = 2(l + 5)

⇒ 25 = 2l + 10

⇒ 2l = 25 - 10

⇒ 2l = 15

⇒ l = 15/2

⇒ l = 7.5 m

∴ Other side of rectangle = 7.5 m

More information about rectangle:-

⇒ $\sf Area \: of \: rectangle = l \times b$

⇒ $\sf Diagonal\: of \: rectangle = \sqrt{l^2 + b^2}$

⇒ Sum of all angles = 360°

⇒ Value of every angle = 90°
