length=8 units
Step-by-step explanation:
- LET,
- A=16 units
- L=a units
- B=a-6 units
- L*B=A
- Replacing value of L with 'a'. and B with 'a-6',
- a(a-6)=16
- a*a-a*6=16
- a^2-6a=16
- a^2-6a-16=0
- a^2-8a+2a-16=0
- a(a-8)+2(a-8)=0
- (a-8)(a+2)=0
- Either,. a-8=0
- first value a=8
- Or,. a+2=0
- second value a=-2(Rejected due to negative)
- therefore, a=L=8
- Length=8 units
