Question

If the length of the triangle is 2 whole 1/3 3whole1/2 and 3/4 . length of the rectangle is 2whole1/3 and width of the rectangle is 1whole3/5 .then what is it perimeter and which one is greater​

Answer 1

Answer

Given ,

Sides of triangle are :

࿇$\rm2 \frac {1 } { 3 }$ = $\rm \frac { 7 } { 3 }$

࿇ $\rm 3 \frac { 1 } { 2 }$ = $\rm \frac { 7 } { 2 }$

࿇ $\rm \frac { 3 } { 4 }$

Sides of rectangle are :

࿇ $\rm2 \frac { 1 } { 3 }$ = $\rm \frac { 7 } { 3 }$

࿇ $\rm 1 \frac { 3 } { 5 }$ = $\rm \frac { 8 } { 5 }$

Perimeter of triangle :

Sum of length of all three side

$\rm \frac { 7 } { 3 }$ + $\rm \frac { 7 } { 2 }$ + $\rm \frac { 3 } { 4 }$

Taking LCM = 12

$\implies \rm \frac { 28 + 42 + 9 } { 12 }$

$\implies \rm \frac { 79 } { 12 }$

$\implies \rm 6.5833 units$

Perimeter of rectangle :

2 ( length + breadth )

$\implies \rm2$ ( $\rm \frac { 7 } { 3 }$ + $\rm \frac { 8 } { 5 })$

Taking LCM = 15

$\implies \rm2$ ( $\rm \frac { 35 + 24 } { 15 })$

$\implies \rm2$ ( $\rm \frac { 59 } { 15 })$

$\implies \rm7.86666 units$

Clearly rectangle has more perimeter than triangle
