Answers

1
What is the area of this triangle?
A = (10 x 6) = 60m2
A = 0.5 (10 x 6) = 30m2
A = (10 ÷ 2)(6 ÷ 2) = 15m2
A = (10 x 6) ÷ 2 = 30m2
2
What is the formula for the area of a circle?
A = 2 π r
A = π r
A = π D
A = π r2
3
What is the formula for the area of a parallelogram?
A = (base x height)2
A = base x height
A = 2 x base + 2 x height
A = (base + height)2
4
What is the area of this rectangle?
A = (3 + 4)2 = 49cm2
A = (4 x 3)2 = 144cm2
A = 4 x 3 = 12cm2
A = 2 x 4 + 2 x 3 = 14cm2
5
What is the formula for the perimeter/circumference of a circle?
C = π D
C = π r
C = 2 π r
C = π r2
6
What is the formula for the perimeter of a rectangle?
P = length + width
P = length + width + length + width
P = length x width
P = 2 (length + width)
7
What is the formula for the area of a triangle?
A = (base + height) ÷ 2
A = (base ÷ 2)(height÷ 2)
A = (base x height)
A = 0.5 (base + height)
8
What is the area of this circle?
A = π x 162 = 804 mm2
A = π x 8 = 25.1 mm2
A = π x 82 = 201 mm2
A = π x 16 = 50.2 mm2
9
What is the perimeter of this rectangle?
P = 2 (3 + 4) = 14 cm
P = 3 + 4 = 7 cm
P = 3 x 4 = 12 cm2
P = 2 + 3 + 2 + 3 = 14 cm
10
What is the formula for the area of a rectangle?
A = length x height
A = 2 x length + 2 x height
A = (length + height)2
A = (length x height)2
