Need to find:
- Perimeter of new square formed?
Solution:
- Side of smaller square = 3cm.
- Side of Bigger square = 9cm
Using formula:
- Perimeter of square = 4 × side
<u>Perimeter of smaller </u><u>square:</u>
⟹ 4 × 3
⟹ 12 cm
<u>Perimeter of Bigger square:</u>
⟹ 4 × 9
⟹ 36cm
Perimeter of new square = Perimeter of Bigger square - Perimeter of smaller square
⟹ 36 - 12
⟹ 24 cm
∴ Perimeter of new square formed is 24 cm.
9.81 or 10 Estimated sum would be 10, add all of them and you get 9.81 which is 10 estimated
Answer:
AC = 20.5
BC = 14.5
Step-by-step explanation:
The distance from C to A is 6 cm longer than the distance from C to B. gives us the following equation
AC = BC +6
We know the distance of the two segments gives us the total segment
AB = AC + BC
The total segment is AB =35
Substituting into AB= 35 and AC = BC+6
AB = AC + BC
35 = (BC+6) + BC
Combing like terms
35 = 2 BC +6
Subtract 6 from each side
29 = 2 BC
Divide by 2
14.5 = BC
Now find AC
AC = BC+6
AC = 14.5+6 = 20.5
