Question

The length f a rectangle excceds it breadth by 2cm and its perimeter is 36 cm find length and breadth​

Answer 1

Answer:

The Length is 10 cm Breadth is 8 cm

Step-by-step explanation:

Gívєn -

Length of the Rectangle = excceds it breadth by 2cm

Perimeter of the Rectangle = 36 cm

Tσ fínd -

Its Length and Breadth

Sσlutíσn -

Let the -

• Breadth be x
• Length be (x + 2)

★ Perimeter = $\boxed{\sf{2(Length+Breadth)}}$

$\sf{\implies} \: 2(x + x + 2) = 36 \\ \sf{\implies} \:2x + 2x + 4 = 36 \\ \sf{\implies} \:4x = 36 - 4 \\ \sf{\implies} \:4x = 32 \\ \sf{\implies} \:x = \frac{32}{4} \\ \sf{\implies} \:x = 8$

Breadth = 8 cm

$\rule{300}{1.5}$

Length =

$\sf{\implies} \:(x + 2) \\ \sf{\implies} \:(8 + 2) \\ \sf{\implies} \:10$

Length = 10

$\therefore$ The Length is 10 cm Breadth is 8 cm

Answer 2

Answer:

let the breath be x

length be x+2

perimeter of rectangle =36

=2 (l+b)=36

=2 (x+2+x)=36

=2x+4+2x=36

=4x+4=36

=4x=36-4

=4x=32

=x=32/4

=x=8

therefore breath=x=8

length=x+2

=2+8=10
