The square root of four is two. To find the square root of four you find out what number, when multiplied by itself will get four. In this case, 2×2=4.
Answer:
30 is 120% of 25
Step-by-step explanation:
30 = 120% of y
× y = 30
After multiplying both sides by 100 and dividing both sides by 120, we have
y = 30 × 
y = 25
The area of a trapezoid can be found with the formula where b1 and b2 are the bases and h is the height. Let's plug in the values that we know and solve for h.
The area would be 63.The steps to how I got that anwser:
1.] Write your formula
A=bh
----
2
2.]Begin by plugging in your measurements
A=7.5 times 16.8
-------------------

3.]Multiply the top two numbers together
A=126
-----
2
4.]Divide to get your final anwser
A=63
Answer:
