Question

A rectanglar sheet of paper is 12 1/2 cm long and 10 3/2cm wide . find the perimeter​

Answer 1

Answer:

the perimeter of this rectangle is 48 cm

Answer 2

GIVEN  :-

• Length of rectangular sheet ( L ) = 12(1/2) cm
• Breadth of rectangular sheet ( B ) = 10(3/2) cm.

TO FIND :-

• The perimeter of rectangular sheet.

SOLUTION :-

$\setlength{ \unitlength}{20} \begin{picture}(3,5) \put(2,2){ \line(1,0){6}}\put(2,2){ \line(0,1){3}}\put(8,2){ \line(0,1){3}} \put(2,5){ \line(1,0){6}} \put(2,1.5 ){ \tt D } \put(8, 1.5){ \tt C } \put(2,5.2){ \tt A } \put(8.2, 5){ \tt B } \put(8.5,3 ){ \displaystyle \tt \dfrac{23}{2} \: cm } \put(4, 5.5){ \displaystyle \tt \dfrac{25}{2} \: cm } \\ \put(8.5,6){\framebox{ \tt @prince5132 }}\end{picture}$

▪︎perimeter if rectangle = 2(L + B)

= 2(25/2 + 23/2)

= 2[(25 + 23)/2]

= 2 × 48/2

= 48 cm

Hence the perimeter of rectangular sheet is 48 cm.

ADDITIONAL INFORMATION :-

▪︎Area of rectangle = Length × breadth

▪︎Perimeter of rectangle = 2(Length + breadth)
