Question

perimeter of rectangle is 160cm, find the breadth and area of it

Answer 1

$\huge\underline\mathrm{SOLUTION:-}$

Correct Question:

• The perimeter of rectangle is 160cm. If the breadth of the rectangle is 30 cm, find its length also find the area of the rectangle.

AnswEr:

• Lengthof the rectangle = 50 Cm.
• Breadth of the rectangle = 1,500 Cm²

Given:

• Perimeter of rectangle is 160 Cm.
• Breadth of the rectangle is 30 Cm.

Need To Find:

• Length of the rectangle = ?
• Area of the rectangle = ?

ExPlanation:

In case 1:

• Find the length of the rectangle = ?

Formula used here:

• Perimeter of rectangle = 2 × (l + b)

Putting the values according to the given formula:

➠ 160 = 2 × (Length + 30)

➠ 160/2 = length + 30

➠ 80 = length + 30

➠ 80 - 30 = length

➠ 50 = length

• Hence, the length of the rectangle is 50 Cm.

In case 2:

• Find the area of the rectangle = ?

Formula used here:

• Area of rectangle = l × b

Putting the values according to the given formula:

➠ 50 × 30

➠ 1,500

• Hence, the area of the rectangle is 1,500 Cm².

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

Additional Information:

What is Perimeter?

• The length of the boundary of a closed figure is called Perimeter.

• Perimeter of rectangle = 2 × (Length + Breadth)
• Perimeter of square = Side × Side

What is Area?

• The measure of the surface enclosed by a closed figure is called Area.

• Area of rectangle = Length × Breadth
• Area of square = Side × Side
