Answer:
The final estimate of √388 is 20.
Step-by-step explanation:
The number provided is:
<em>x</em> = 1388
Estimate the square root of 1388 as follows:
15² = 225
16² = 256
17² = 289
18² = 324
19² = 361
20² = 400
So, we now know that the square root of 388 lies between 19 and 20.
Check for 19.5²:
19.5² = 380.25
Check for 19.6²:
19.6² = 384.16
Check for 19.7²:
19.7² = 388.09 ≈ 388
The square root of 388 is closer to 19.7 or is approximately 20.
Thus, the final estimate of √388 is 20.
The equivalent of 0.25 kilometers to centimeter is 25,000 centimeters. It is computed by converting first 0.25 km in to meters, with that 1 km has 1,000 meter and by that we could say that in 0.25 km there is 250 meter. THen converting meter into cm, with that 1 m has 100 cm, and by that 250 meters there is 25,000 cm.
Answer:
We first ALWAYS have to split the figure apart from each other,
lets split it into a triangle and a square!
Let's find the area of the triangle:
20(height) x 20(base) = 400!
400 x 1/2 (just dividing by 2) = 200!
*Remember* Formula of a triangle is:
B(base) x H(height) x 1/2 (basically dividing by 2)
Now time to find the area of the square!
20 x 20 = 400!
Now let's add both their areas:
400 + 200 = 600!
Step-by-step explanation:
