Answer» Answer: BREADTH = 16m length =l= 2b+1=2×16+1=32+1=33m Step-by-step EXPLANATION: Let the breadth =b m length = l =(2b+1)m area =528m² l×b= 528 (2b+1)b-528=0 2b²+b-528=0 2b²+33b-32b-528=0 b(2b+33)- 16(2b+33)=0 (2b+33)(b-16)=0 2b+33=0 or b-16=0 b should not be zero therefore b-16=0 b=16 breadth = 16m length =l= 2b+1=2×16+1=32+1=33m |
