Question

the length of a rectangle exceeds its breadth by 4 m find the dimensions of the rectangle if its perimeter is 084 m​

Answer 1

Answer:

l = 23m

b = 19m

Step-by-step explanation:

let,

breadth= b

ATQ, length= l = b+4m

P of rectangle = 2 ( l + b ) = 084m

=> 2 ( b + 4 + b )                  = 084m

2 ( 2b + 4 )                           = 084m

( 2b + 4 ) = 84/2 = 42

2b = 42 - 4 = 38

b = 38/2 = 19m

l = b + 4 = 19 + 4 = 23m

P.S.  hope it helps !
