QUESTION:-

the AREA of a rectangular sheet is 500cm .if the length of the sheet is 25CM , what is the breadth ? also find the perimeter of the rectangular sheet

Answer:-

  • The breadth of rectangle is 20 cm
  • The perimeter of rectangle is 90 cm.

To find:-

  • Perimeter and breadth of rectangle

Solution:-

  • Area = 500 cm²
  • Length (l) = 25 cm
  • Breadth (b) = ?

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \large{ \mathfrak{ \star \:  \:  \: {area = l \times b}}}

ACCORDING to question,

\large{ \tt :  \implies \:  \:  \:  \: 25 \times b = 500}

\large{ \tt :  \implies \:  \:  \:  \: b =  \frac{500}{25} } \\

\large{ \tt :  \implies \:  \:  \:  \: b = 20 \: cm}

Thus,

  • The breadth of rectangle is 20 cm

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \large{ \mathfrak{ \star \:  \:  \: {perimeter = 2(l + b)}}}

\large{ \tt :  \implies \:  \:  \:  \:  \: perimeter  = 2(25 + 20)}

\large{ \tt :  \implies \:  \:  \:  \:  \: perimeter = 2 \times 45}

\large{ \tt :  \implies \:  \:  \:  \:  \: perimeter = 90 \: cm}

  • The perimeter of rectangle is 90 cm.
