Question

The length of a rectangle is 8 m more than its breadth. If its perimeter is 128 m, find its length and
breadth
​

Answer 1

Answer:

Length = 68 , Breadth = 60

Step-by-step explanation:

p = perimeter , l = Length , B = Breadth

p = 2[l+b] =128

l = b+8

p = 2 [ b+8+b] = 128

2b+ 8 = 128

2b = 128 - 8

2b= 120

b = 60

l = 60 + 8

l =68

Answer 2

Answer:

l = 36m, b = 28m

Step-by-step explanation:

l = 8+b

l+l+b+b =128m

2l+2b = 128m

2 (8+b)+2b = 128m

16+2b+2b =128m

16+4b =128m

4b = 128-16

4b = 112

b = 112÷4

b = 28m

l = 8+28

l = 36m
