Question

length and breadth of a rectangle are 4 2by 3 its a mixed fraction and 7 1 by 5 cm find its perimeter

Answer 1

Convert it into proper fraction =36/5&14/3

As we know ,perimeter of rectangle =2(l+b)=2(36/5+ 14/3)

Lcm of 5&3 is 15 =2(36*3+ 14*5/15)

2(108+70/15)

2(178/15)

2*178/15=356/15 or 23.7

Answer 2

Hey friend your answer is
~~~~~~~~~~~~~~~~~~~~~~~
ACCORDING TO THE QUESTION
•••••••••••••••••••••••••••••••••••••••
Length =4⅔
Breadth =7 whole 1/5

Conversion into PROPER fraction.
Length =4⅔
=14/3
Breadth=7whole 1/5
= 36/5

To find it's perimeter of rectangle the formula is :-2(l+b)
As the length and breadth given
so,
2(14/3+36/5)

Finding the L. C. M
2(70+108/15)
=2(178/15)
=356/15
=23.7

•°•Perimeter is 23.7cm
