Question

A rectangular sheet of paper is 25/2 cm long and 32/3 cm wide. Find its perimeter.

pls give me a full an answer​

Answer 1

Answer:

perimeter =2(a+b)

a=25/2

b=32/3

then the solution is =2(25/2+32/3)

=2(75+64/6)

=2×139/6

=139/3

Answer 2

Given,

Length of rectangular sheet (a) $\[ = \frac{{25}}{2}cm\]$

Width of rectangular sheet (b) $\[ = \frac{{32}}{3}cm\]$

Solution,

Consider the length and width of the rectangular sheet is a and b. Then perimeter of rectangular sheet,

$\[ = 2\left( {a + b} \right)\]$

Calculate the perimeter of the rectangular sheet,

$\[ = 2\left( {\frac{{25}}{2} + \frac{{32}}{3}} \right)\]$

$\[ = 2\left( {\frac{{25 \times 3 + 32 \times 2}}{{2 \times 3}}} \right)\]$

$\[ = \left( {\frac{{75 + 64}}{3}} \right)\]$

$\[ = \frac{{139}}{3}\]$

$\[ = 46\frac{1}{3}cm\]$

Hence the perimeter of rectangular sheet is $\[ 46\frac{1}{3}cm\]$
