Answer:

$length = x + 4 \\ breadth = x \\ perimeter = 40 \\ 2(x + 4 + x) = 40 \\ 2(2x + 4) = 40 \\ 4x + 8 = 40 \\ 4x = 40 - 8 \\ 4x = 32 \\ x = \frac{32}{4} \\ x = 8$

this is the right answer

meJatin: its showing reported

wwwsmm026: The perimeter of rectangle is 40 and the length and Breadth will be different understand

wwwsmm026: you did not give nice explanation

meJatin: bro perimeter is 2(length + breadth) = 2(12+8) = 2(20) = 40

meJatin: the answer is right

meJatin: I've given in the starting breadth = x and length = x+4

wwwsmm026: Answer is right I accept it but the method is wrong according to linear equations

wwwsmm026: it is word problems

meJatin: ok bro if you don't like report it
