What number of 2 cm squares' worth of sides are there on the surface of a 24 cm by 8 cm rectangle?
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
45 cm2 is the area of a rectangle. Its width in centimeters, given its length of 9 cm
Correct Answer: 5
Area = L × W
45 = 9 × W
W = 45 ÷ 9 = 5
Six inches is the length and four inches is the width of a rectangle. The region is in2.
Correct Answer: 24
A rectangle's area is equal to L × W, where L stands for length and W for width.
A triangle whose single angle is more than 90 degrees.
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.
A square has a 24 cm perimeter. The square has an area of cm².
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
What is the number of sides in the triangle?
Correct Answer: 3
A polygon with three sides is called a triangle. Thus, option three is the right response.
One of the polygons is an octagon. What is the number of its sides?
