Answer:
11 units
Step-by-step explanation:
Since <em>∆ABC is isosceles, it means that at least two sides are congruent/equal in length</em>.
<em>Sides CA and AB are congruent</em>, since BC is the base. So, <em>CA = 4</em>.
That means the perimeter is <em>4 + 4 + 3 </em>= 11 un

Answer:
correct
Step-by-step explanation:
Answer:
Obj B, by 1 g/cm^3
Step-by-step explanation:
Obj A = 12g / 8cm^3 = 3g / 2cm^3 = 1.5 g/cm^3
Obj B = 20g / 8cm^3 = 5g / 2cm^3 = 2.5 g/cm^3
2.5 - 1.5 = 1 g/cm^3
