How can estimation help me to find the area of a rectangle or square

Answers

Answer 1

Answer: If you know your multiplication tables it becomes quite simple to find the area of a rectangle. You can round your lengths up or down accordingly to find the area of a figure. For example, what if we had a square 2.334" by 3.574"? The 2.334 rounds down to 2 and the 3.574 rounds up to 4. Now we have a 2 by 4" rectangle. Now we find our area. 2*4=8 inches squared. Does that answer your question?

aright i figured it out:)
step one we need to remember PEMDAS
P : (parentheses)
E : exponents ³
M : multiplication x
D : division ÷
A : addition +
S : subtraction -
i always remembered this by using this one sentence
"P"lease "E"xcuse "M"y "D"ear "A"unt "S"ally
but that's a different topic;) lets solve our problem
6.53 + 1.4 ÷ (0.7 + 0.1)
well lets follow along with out PEMDAS and first i see parentheses as our first step. So lets solve what we have within our Parentheses.
0.7 + 0.1 = 0.8 now lets plug in what we have
6.53 + 1.4 ÷ 0.8 now i see another step we can do here and thats division
1.4 ÷ 0.8 = 1.75 now lets plug in what we finally have
6.53 + 1.75 = 8.28
answer? 8.28
if this was helpful
then don't forget too
MARK ME BRAINLIEST! :D

6.53+1.4/(0.7+0.1)=6.53 + 1.4/.8=6.53 + 1.75=8.28

Answer: 6.53+1.4/(0.7+0.1)=8.28

Ruiz needs to buy a countertop for a kitchen. He calculated the area to be 16 square feet. The actual area is 15.4 square feet. What is Ruiz's percentage error? A.0.6%
B.3.75%
C.3.9%
D.6%

Answers

Percentage error $=(error)/(actual measurement) * 100$
Here error = 16 - 15.4 = 0.6
Therefore, percentage error $=(0.6)/(15.4) * 100=0.039 * 100$
=3.9%

Answer:

3.9

Step-by-step explanation:

16 - 15.4 = 0.6 ={0.6}{15.4} *100=0.039 * 100 =3.9%
