The answer is 12 because it’s a circle and that dot in the middle is the radius. so the radius is 6 which mean the diameter is 2x that making it 12
Answer:
l=11
b=8
Step-by-step explanation:
Let l=x+3
b=x
Perimeter=38
i.e 2l+2b=38
2(l+b)=38
2(x+3+x)=38
2(2x+3)=38
4x+6=38
4x=38-6
x=32/4
x=8
Im not entirely sure but wouldnt the equation be (x)(x-6)?
