Correct Answer: 5
Area = L × W
45 = 9 × W
W = 45 ÷ 9 = 5
Correct Answer: 36
Perimeter is 4 × a where a is the side of the square
4 × a =24
a = 24 ÷ 4 = 6
Area = a × a = 6 × 6 = 36 cm2
Correct Answer: 48
The area of the square is 2 × 2 = 4 cm2
The area of the rectangle is L × W = 24 × 8 = 192 cm2
The number of squares is 192 ÷ 4 = 48
Correct Answer: Obtuse triangle
A triangle with one angle larger than 99 degrees is called an obtuse triangle. It is not the same as an equilateral triangle, which has all angles equal to 60 degrees, or an acute triangle, which has all angles less than 99. A triangle that has two equal-length sides but not necessarily an angle bigger than 90 degrees is called an isosceles triangle. Thus, obtuse triangle is the right response.
Correct Answer: 8
An octagon is a polygon with eight sides.
Correct Answer: 3
A polygon with three sides is called a triangle. Thus, option three is the right response.
Correct Answer: 24
A rectangle's area is equal to L × W, where L stands for length and W for width.
