Question

when the lenght is 3more than breadth in rectangle the perimeter in terms of b​

Answer 1

Answer:

Let the width be  

x

and length be  

(

x

+

3

)

.

now, we have,

P

e

r

=

(

l

+

w

)

58

c

m

=

x

=

4

c

m

∴

x

=

13

c

m

So, width =  

x

=13 cm

and, length =  

x

+

3

= 13 cm +3 =16 cm

Answer 2

Answer:

Let the, Breath of Rectangle = x then, Length of Rectangle = x+3 [As in the question it is given that, Length is 3 more than Breadth]. As per Both the equation, => 2(x+x+3) = 30 m [Perimeter is the sum of all sides]. => 2(2x+3) = 30 m => 4x = 30-6 m => 4x = 24 m => x = 24/4 m => x = 6 m Hence, Breadth = x = 6 m Length = x+3 = 6+3 m = 9 m
