Question

Find the Breadth of the Rectangle if Perimeter of Rectangle is 20cm and length is 5cm?. ​

Answer 1

Answer:

$\huge\star\underline{\mathtt\color{aqua}{❥a} \mathfrak\color{yellow}{n }\mathfrak\color{blue}{s} \mathbb\color{purple}{ w} \mathtt\color{orange}{e}\mathrm\color{red}{r}}$

W= Perimeter÷2-length

=20÷2-5

=5

hope it helps :)

Answer 2

Given:-

• Perimeter of the rectangle is 20cm.

• Length of the rectangle is 5cm.

To Find:-

• Find the breadth of the rectangle.

Concept:-

• Let's go through the concept first. Concept used here is Perimeter of a Rectangle.Substitute the values in the equation and solve it.

Formulae Applied:-

• Perimeter of a Rectangle = 2(l + b)

Solution:-

Let the breadth be b

Given that,

Perimeter of the rectangle is 20cm.

Length of the rectangle is 5cm.

According to the question we have,

Perimeter of a Rectangle = 2(l + b)

= 2(l + b)

= 2(l + b) = 20

= 2(5 + b) = 20

= 5 + b = 20/2

= 5 +b = 10

= b = 10 - 5

= b = 5

= b = 5cm

Hence,

The breadth of the triangle is 5cm.

Verification:-

2(5 + b) = 20

b = 5

Substitute the value of b in the equation above

= 2(5 + 5) = 20

= 2(10) = 20

= 2 × 10 = 20

= 20 = 20

= LHS = RHS

Hence,

It is verified.
