Question

The perimeter of a rectangle is 13 cm and it’s width is 3/24 cm . Find it’s length in cm

Answer 1

$\sf{Answer}$

Perimeter of rectangle =2× length +breadth

Now perimeter is 13

2(2$\frac{3}{4}$ +b)=13

2($\frac{11}{4}$+b)=13

$\frac{11}{4}$+b=$\frac{13}{2}$

b=$\frac{13}{2}$-$\frac{11}{4}$

b=$\frac{15}{4}$cm

so its length is$\frac{15}{4}$cm

Answer 2

Answer:

GIVEN :

PERIMETER OF RECTANGLE = 13 CM

BREADTH OF RECTANGLE = 3 / 24 CM

Step-by-step explanation:

TO FIND :

LENGTH OF RECTANGLE = ?

SOLUTION :

PERIMETER OF RECTANGLE = 2 × ( L + B )

13 = 2 × ( L + 3 / 24 )

13 / 2 = L + 3 / 24

( TAKE LCM )

13 / 2 = 24 L + 3 / 24

13 / 2 × 24 = 24L + 3

156 = 24L + 3

153 = 24L

L = 153 / 24

L = 6.375 CM

THEREFORE LENGTH OF RECTANGLE = 6.375 CM
