Here are a couple of practice questions that I would like you to do!Good Luck!Brandi

• 1.

### If we have a triangle with the side lengths of 3, 4, 5, find the perimeter.

• A.

15

• B.

60

• C.

12

• D.

23

C. 12
Explanation
The perimeter of a triangle is the sum of the lengths of its sides. In this case, the lengths of the sides are given as 3, 4, and 5. Adding these lengths together, we get 3 + 4 + 5 = 12. Therefore, the perimeter of the triangle is 12.

### If square has side lengths of 6 the perimeter will equal 24.

• A.

True

• B.

False

A. True
Explanation
If a square has side lengths of 6, it means that all four sides of the square are 6 units long. To find the perimeter of a square, we add up the lengths of all four sides. In this case, 6 + 6 + 6 + 6 equals 24. Therefore, the statement "If a square has side lengths of 6, the perimeter will equal 24" is true.

Rate this question:

• 3.

### A pentigon has a perimeter of 30 what must each side of the pentigon equal?

6
Explanation
Since a pentagon has five sides, and the perimeter is the sum of all the sides, we can divide the perimeter (30) by the number of sides (5) to find the length of each side. Therefore, each side of the pentagon must equal 6.

Rate this question:

• 4.

### Give the perimeter of a rectangle with length 8 and width 4.

• A.

24

• B.

32

• C.

55

• D.

1

A. 24
Explanation
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the length of the rectangle is 8 units and the width is 4 units. To find the perimeter, we add twice the length and twice the width. Therefore, the perimeter of this rectangle is 2(8) + 2(4) = 16 + 8 = 24 units.

Rate this question:

• 5.

### If a triangle has sides with length 7 the perimeter will be 20.

• A.

True

• B.

False

B. False
Explanation
The statement is false because the perimeter of a triangle is the sum of the lengths of its sides. If a triangle has sides with length 7, the perimeter would be 7 + 7 + 7 = 21, not 20.
