Answer:
Breadth is 32 cm
Step-by-step explanation:
Given,
l = b + 6
Area of rectangle = length x breadth
1216 = (b + 6) x b
= + 6 b
- 6 b + 1216 = 0
By factorization
+ 32 b - 38 b + 1216 = 0
b( b + 38 ) - 32 ( b + 38 ) = 0
b = - 38 or b = 32
So, b = 32 [ Length can't be negative number ]
Now, Length is 38 cm and Breadth is 32 cm
Verification:
Area = l x b
area = 38 x 32 = 1216
