Answer:
A
Step-by-step explanation:
the height a creates with half of the baseline (5) and a leg (10) a right-angled triangle, and we can use Pythagoras to calculate a.
c² = a² + b²
c being the Hypotenuse (the side opposite of the 90° angle, so in our case the 10 side).
10² = a² + 5²
100 = a² + 25
75 = a²
a = sqrt(75) = sqrt(3×25) = 5×sqrt(3)

Answer: 12.32%
Step-by-step explanation:
1.
is the original long side and
is the original short side.
2. The area of the original rectangle is
.
3. The rectangle is extended 4% on the long sides and 8% on the short sides. therefore, the new long side is:

4. And the new short side is:

5. The new area is:

6. The percentage of increase is calculated by substracting the new area and the original area:

7. The result is:
(0.1232)(100)=12.32%
