A square has an area of 121 square centimetres.
What is its perimeter?
2 answers:
Answer:
<u>44 cm</u>
Step-by-step explanation:
<u>Finding Side Length</u>
- Area = (Side length)²
- Take the square root on each side
- Side length = √121
- Side length = 11 cm
<u>Perimeter</u>
- A square has 4 sides
- Therefore, the perimeter is 4 times the side length
- 4 × 11
- <u>44 cm</u>
Answer:
44 cm
Step-by-step explanation:
The area of a square is the square of the side length. This means the side length is the square root of the area.
s = √A = √(121 cm²) = 11 cm
The perimeter of a square is the sum of its side lengths. There are 4 equal-length sides, so the perimeter is 4 times the length of one side:
P = 4s = 4(11 cm)
P = 44 cm
The perimeter of the square is 44 cm.

You subtract 5 1/4 (5.25) - 3 3/4 (3.75) = 1 1/2 (1.5)
One “x” tile and five “1” cubes
Answer:
$10.71
Step-by-step explanation:
y × 35 = 3.75 × 100
35y = 375
35y ÷ 35 = 375 ÷ 35
y = 10.7142857143
10.7142857143 round to 10.71
Answer:
Markup= 1.81
Sale price =9.06
Step-by-step explanation:
The markup is the original prices times the markup rate
markup = 7.25 * 25%
= 7.25 * .25
=1.8125
We round this to the nearest cent
=1.81
The new sale price will be the original price + the markup
7.25+1.81
9.06
