Question

Find the surface area and round to the nearest hundredths place when necessary.

Answer 1

Let's find the area of 1 triangle (this may not be the formula but I'm doing it in a more easier way).

20(base) x 10.5(height) = 210

210 divided by 2 ( x 1/2) = 105

Since there are 4 sides we must multiply the area of 1 triangle four times! Since there are 4 sides of triangles.

105 x 4 = 420

Oh and I almost forgot! We need to find the area of the square below!

20 x 20 = 400!

Now we add both areas of all the triangles and the area of the bottom square:

420 + 400 = 820 in2 is your answer. (we use the unit 2 since we are finding areas and adding them up)

Formula of a triangle:

BH x 1/2

B(base) x H(height) x 1/2 (basically just dividing by 2)

Answer 2

The question pertains to mathematics, focusing on unit conversion and measurement precision. Millimeters are converted to meters, then rounded to the nearest hundredth. Significance in answers is matched to the least precise measurement to maintain accuracy.

The student has asked about converting millimeters to meters and about finding the surface area, which would involve mathematics, specifically dealing with measurements and unit conversion. The task involves rounding to the nearest hundredth place when converting and ensuring the precision matches the least precise measurement given in problems.

Write each decimal conversion. Round to the nearest hundredth when necessary:

• 1.1 mm = 0.0011 m
• 2.5 mm = 0.0025 m
• 3. 10 mm = 0.01 m
• 4. 15 mm = 0.015 m

When solving problems and converting measurements, it's essential to

• Express your answers to the correct number of significant figures.
• Use the proper units for your answers.
• Attend to precision by rounding your final answer to match the least precise measurement used in your calculations.

For example, if you are adding or subtracting and one measurement is to the tenth place and another is to the hundredth place, your final answer should be rounded to the tenth place.

Using mental math and your understanding of fundamental units, approximate the area of a regulation basketball court. The process used could be an estimation based on the court's typical dimensions, usually around 28m by 15m, yielding an approximate area of 420 square meters.
