Construct a quadrilateral. Label BASE and HEIGHT.
Needs 4 sides!
Calculate the Area and Perimeter of a square with side length 4m.
P = 4 + 4 + 4 + 4 =16m
A = 4 x 4 = 16m2A yard has a perimeter of 30m. If fencing costs $6 /m, how much will the yard's fencing cost?
30 x 6 = $180
It will cost $180.
Convert the following measurements into cm.
A) 55mmB) 3m
A) 55mm / 10 = 5.5cm
B) 3m x 100 = 300cm
Construct a Square. Label BASE and HEIGHT.
Need 4 congruent sides and 4 right angles.
Calculate the area of a Parallelogram with BASE = 6m and HEIGHT = 8m.
A = b x h = 6 x 8 = 48m2
Name 2 characteristics of a Square.
1. 2 sets of 2 parallel sides.
2. 4 right angles
3. All sides are congruent
Round the following to the nearest tenths.
A) 72.31
B) 0.385
A) 72.30
B) 0.400
Construct a Parallelogram. Label BASE and HEIGHT.
Need 2 sets of parallel sides.
Calculate the area of a trapezoid with HEIGHT = 5m, and BASES = 3m and 4m.
A = (B + b) x h / 2
A = (3 + 4) x 5 / 2
A = 7 x 5 / 2
A =35 / 2
A = 17.5 m2
If grass costs $0.50 per m2, how much would it cost to cover a rectangular backyard with dimensions of 12m and 16m.
Area = b x h = 12 x 16 = 192 m2
Cost = 192 x 0.50 = $96
It would cost $96.
What is Mr. Bienzle's age?
Construct an Isosceles Triangle. Label BASE and HEIGHT.
Need 2 sides to be congruent!
Height is perpendicular to Base!
Find a possible BASE and HEIGHT combination that would give a triangle an area of 15m2.
15 x 2 = 30 (need 2 numbers that multiply to 30).
Base / Height = 3m and 10m
Base / Height = 5m and 6m
Base / Height = 15m and 2m
Base / Height = 30 and 1m
A table cloth has dimensions of 6m by 6m. A square table has an area of 25m2. Will the table cloth fit the table?
Square root of 25 is 5m
The table has dimensions 5m by 5m.
The table cloth will fit.
Identify the following definition:
A parallelogram with 4 congruent sides.
Rhombus.
Construct a Rhombus. Label BASE and HEIGHT.
Need 4 congruent sides!
Determine the HEIGHT for a trapezoid with: an AREA of 27m2 and BASES of 3m and 6m.
27 x 2 = 54
3 + 6 = 954 / 9 = 6m
Height is 6m.
What is the Perimeter of a rectangular field if one side is 8km and the area is 32km2?
32 / 8 = 4km
4 + 8 + 4 + 8 = 24km
The perimeter is 24km.
What is your best guess at the area of the classroom in m2? (Closest guess wins).
68.65m2
