2(x+y)=16,
x+y=16/2=8
y=8-x
x*y=15
x(8-x)=15
8x-x^2=15
x^2-8x+15=0
x^2-3x-5x+15=0
x(x-3)-5(x-3)=0
(x-3)(x-5)=0
x=3,5
when x=3
y=8-3=5
when x=5
y=8-5=3
length=5 meters
width=3 meters.
There is no cone to surface
Answer:
144 u²
Step-by-step explanation:
first we need to find lateral area
La=Ph
LA=(12)(11)
LA= 132 u²
SA= Ph + 2B
SA= 132 + 2(6)
SA= 144 u²
