Answer:
21 % increase
Step-by-step explanation:
Lets imagine the sides of the rectangle are 100 & 200 cms.
The area would be 100 x 200 = 20000cm^2
If we added 10% onto each side, the sides would now be 110 & 220 cms.
The area would be 110 x 220 = 24200cm^2
We can now find percentage change:
= 21/100 = 21% increase.
The reason we can just pick random values of sides to do this question with is because we worked out percentage change, which will be the same no matter the proportion of the sides.
Hope this helped! Let me know if you have any questions :)

Answer:
184.8 cubic cm
Step-by-step explanation:
The formula for the volume of a pyramid is
V = (1/3)(B)(h) where B is the area of the base, and h is the height
We are given B = 44 cm² andh = 12.6cm
Plug them into the formula and simplify...(I'm assuming you are allowed to use a calculator for these problems)
V = (1/3)(44cm²)(12.6cm)
<h2> V = 184.8 cm³ or 184.8 cubic cm</h2><h2 />
Answer:
$552.5
Step-by-step explanation:
Lets use the I=PRT formula
Where
I=interest
P=principal(500)
R=rate(0.035)
And
T=time(3)
So
I=500*0.035*3
I=52.5
We need to add the interest and the principal to get the total amount
52.5+500=552.5
