Mathematics: Two cross-roads of width 5 m pass through the middle of a rectangle of dimensions30 m by 20 m. One of the roads is parallelto the length and the other is parallelto the breadth. Determine the cost ofconstruction of the roads if 1 sq. m costsRs 15.Please help me solve this with steps .

(m-n)Step-by-step explanation:1st expression= =(m-n) (m+n)2nd expression==(m-n)(m-n)therefore H.C.F=(m-n)taking common (m-n)...

(m-n)

Step-by-step explanation:

1st expression=

$= {m}^{2} - {n}^{2} \: \: \: \: \: \: \: \: \: \:$

=(m-n) (m+n)

2nd expression=

$({m - n})^{2}$

=(m-n)(m-n)

therefore H.C.F=(m-n)

taking common (m-n)
