AREA
What does AREA mean in geometry?
AREA is the measurement of the amount of space inside a 2D shape or surface.
What does PERIMETER mean in geometry
PERIMETER is the total distance around the boundary of a 2D shape.
What is a fraction?
A fraction represents a part of a whole. It has two parts: a numerator (top number) and a denominator (bottom number). The numerator shows how many parts we have, and the denominator indicates the total number of equal parts in the whole.
How do you calculate the area of a rectangle?
To find the area of a rectangle, multiply its length by its width: Area = Length × Width.
How do you calculate the perimeter of a rectangle?
Answer: To find the perimeter of a rectangle, add up all four sides: Perimeter = 2 × (Length + Width).
Simplify the fraction 12/16.
Answer: To simplify the fraction, find the greatest common divisor (GCD) of the numerator and denominator. In this case, GCD(12, 16) = 4. Divide both the numerator and denominator by 4: 12/16 simplifies to 3/4.
If a rectangle has a length of 8 units and a width of 5 units, what is its area?
Answer: Area = 8 units × 5 units = 40 square units.
If a rectangle has a length of 8 units and a width of 5 units, what is its perimeter?
Answer: Perimeter = 2 × (8 units + 5 units) = 2 × 13 units = 26 units.
Convert the fraction 3/5 into a decimal.
Answer: Divide the numerator (3) by the denominator (5): 3 ÷ 5 = 0.6. So, 3/5 as a decimal is 0.6.
If a square has a side length of 6 units, what is its area?
Answer: Area = 6 units × 6 units = 36 square units.
If a square has a side length of 6 units, what is its perimeter?
Answer: Perimeter = 4 × 6 units = 24 units.
Multiply 2/5 by 3/4.
Answer: To multiply fractions, multiply the numerators together and the denominators together: (2/5) × (3/4) = (2 × 3) / (5 × 4) = 6/20. Simplify the fraction: 6/20 simplifies to 3/10.
What is the formula to find the area of a triangle?
The area of a triangle can be calculated using the formula: Area = (Base × Height) ÷ 2.
What is the formula to find the perimeter of a triangle?
Answer: The perimeter of a triangle is the sum of the lengths of its three sides: Perimeter = Side1 + Side2 + Side3.
Which fraction is greater: 3/5 or 4/7?
Answer: To compare fractions with different denominators, find a common denominator. In this case, the common denominator is 35 (the product of 5 and 7). Convert both fractions to have the same denominator: 3/5 = 21/35 and 4/7 = 20/35. Now it's clear that 21/35 is greater than 20/35.
