Question

length of a rectangle exceed its breath by 6cm . if its perimeter is 64 m find the length and breadth

Answer 1

l=x+6
b=x
p=64
2(l+b)=64
2{x+6+x}=64
2x+12+2x=64
x=13
l=x+6=13+6=19
b=x=13

Answer 2

$\bold {Answer:}$

$\bold {let b = x+6m}$

$\bold { perimeter given = 64m:}$

$\bold {perimeter of rectangle =2(l+b)}$

length =x m

2( x +6+x ) =84

6+2x =84

6+2x = 84 /2

6 +2x = 42

2x = 42 -6

2x = 36

x = 36 / 2

x= 18m

length = 18m
breadth = x +6 = 18 +6 = 24m
