Perimeter/Area
Find the perimeter and area of the rectangle. Write an equation to show how you found each of these measurements. Label your answers with the correct units.
Perimeter: 6 + 6 + 9 + 9 =30 feet
Area: 6 x 9 = 54 square feet

A.) 3 + 5 = a
B.) 3 × 5 = a
C.) 3 + 3 + 5 + 5 = a
D.) 5 ÷ 3 = a
B.) 3 x 5 = a

What is the name of this shape?
Trapezoid
The perimeter of this polygon is 23 meters. What is the length of the side labeled s? Write one or more equations to show how you got your answer.
Side s is 3 meters long
10 + (2+4+4) = 20
23 - 20 = 3 meters

What is a similarity between a trapezoid and a rhombus?
Word Bank:
-angles -acute angles -closed figure -congruent -length -line of symmetry -obtuse angles -open figure -parallel -quadrilateral -right angles -sides -side lengths -straight -symmetrical
Some similarities:
Both have 4 sides.
Both have at least one pair of parallel sides.
Both have one pair of acute and one pair of obtuse angles.
Farmer Brown built a square pen for his pigs. One of the side lengths of the pigpen is 7 feet. What is the perimeter of the pigpen? What is the area of the pigpen? Use numbers, labeled sketches or words to solve this problem. Label your answers with the correct units.
perimeter: 7 + 7 + 7 + 7 = 28 feet
area: 7 × 7 = 49 sq. ft.
The perimeter of the pigpen is 28 ft. The area of the pigpen is 49 sq. ft.
Look at the picture. Which numbers are rhombuses but also not squares?
3, 5, 6
What is a difference between a trapezoid and a rhombus?
Word Bank:
-angles -acute angles -closed figure -congruent -length -line of symmetry -obtuse angles -open figure -parallel -quadrilateral -right angles -sides -side lengths -straight -symmetrical
Some differences:
-The trapezoid has one pair of parallel sides; the rhombus has two pairs.
-The rhombus has 4 congruent sides, while the trapezoid can have 0 to 3.
-The rhombus has 2 lines of symmetry. The trapezoid has only 1. (Note: While trapezoids may have 0 lines of symmetry, the one shown has 1.)
David measured his bedroom and made a sketch map. Use the information on David’s sketch map to find the area of the room. Show all your work, including any marks you need to make on the map.
(8 × 10) + (4 × 3) = 80 + 12 = 92
The area of David’s bedroom is 92 square feet.
