Question

the length of a rectangulae field is 400 metres the length of field is 26 metres more than the breadth calculate the length and breadth​

Answer 1

$\mathcal\pink{perimeter\:of \:the\:rectangular\:field}$

$= 400metre$

$let \: breadth \: of \: the \: field \: = x$

$then \: length \: of \: the \: field \: = x + 26$

$perimeter \: of \: the \: rectangular \: field \: = 2(length + breadth)$

$2(x + x + 26) = 400$

$2x + 26 = \frac{400}{2}$

$2x + 26 = 400$

$2x = 200 - 26$

$2x = 174$

$x = \frac{174}{2}$

$x = 87$

$breadth = 87metre$

$length \: = 87 + 26 metre$

$length = 113metre$

Answer 2

Answer:

length = x+26

breadth=x

perimeter=400m

perimeter of rectangle= 2(l+b)

2(l+b)=2(x+x+26)

400=2(2x+26)

2(2x+26)=400

2x+26=400/2

2x+26=200

2x=200-26

2x=174

x=87

breadth=x=87m

length=x+26=87+26=113m
