Question

If the area of a rectangle is 102 sqcm If it's length is 17 cm . what is it's perimeter.


( In short )​

Answer 1

Answer:

46cm

Step-by-step explanation:

P=2l+2A

l=2·17+2·102

17=46cm

Answer 2

Question:

If the area of a rectangle is 102 sqcm If it's length is 17 cm, Then, find it's perimeter.

Analysis:

Rectangle: A rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal. A parallelogram containing a right angle. A rectangle with four sides of equal length is a square.

☆ Area of Rectangle = Length × Breadth

☆ Perimeter of Rectangle = 2(l+b)

Solution:

Given,

Area of Rectangle = 102 cm²

Length = 17cm

Let's Breadth be 'b'

$→\;{\sf{17×b = 102}}$

$→\;{\sf{b = \frac{102}{17}}}$

$➝\;{\bf{b = 6}}$

.:. Breadth of Rectangle = 6cm

Perimetre of given Rectangle

$→\;{\sf{2(17+6)}}$

$→\;{\sf{2(23)}}$

$➝\;{\bf{46}}$

Perimetre of Rectangle ◕➜ $\Large{\red{\mathfrak{46cm}}}$
