Question

perimeter 390m, breadth of rectangle 65m. find the length of rectangle

Answer 1

Given :

Perimeter = 390 m

breadth = 65 m

length = ?

perimeter = 2(length + breadth)

390 = 2(l + 65)

390 = 2l + 130

2length = 390 - 130

2length = 260

Length = 260/2

Length = 130.


Hence :

$\bold{Answer : Length \: = \: 130 \: m}$

Here's , Your Answer :-

=) Given ,
Perimeter = 390 m

breadth = 65 m 

To find :- Length = ?

we know ,
Perimeter = 2(length + breadth) 

putting the values .

390 = 2(l + 65) 

390 = 2l + 130 

2 l = 390 - 130 

2 l= 260 

So , Length = 260/2 

Length = 130. (ans.)
