Introduction to 4th grade math:
In 4th Grade mathematics, we learn about basic numbers, numerals, letters, integers and area of the different shapes. It provides basic idea to the students for solving the simple math problems. Topics under 4th grade mathematics is given below,
Numbers and its operations
Fractions and mixed numbers
Addition and subtraction
Division and multiplication
Geometrical shapes and areas
Algebraic expressions and equations
Logical reasoning
Charts and graphs
Example problems for 4th grade math area
4th grade math problem 1:
Find the area of the square with the side length of 19 cm.
Solution:
Given, side length (a) = 19 cm
Formula:
Area of the square = a2
Substitute the given side length value in the above formula, we get
Area of the square = 192 cm^2
= 361 cm^2
Answer:
Area of the square is 361 cm^2
4th grade math problem 2:
Find the area of the rectangle with the side length of 34 cm and width is 18 cm.
Solution:
Given, side length (l) = 34 cm and width (w) = 18 cm
Formula:
Area of the rectangle = length * width
Substitute the given side length and width values in the above formula, we get
Area of the rectangle = 34 * 18 cm^2
= 612 cm^2
Answer:
Area of the rectangle is 612 cm^2
4th grade math problem 3:
Find the area of the circle with the radius 42 cm.
Solution:
Given, radius of the circle (r) = 42 cm
Formula:
Area of the circle = pr2
Substitute the given side length value in the above formula, we get
Area of the circle = (p * 422) cm^2
= 1764p cm^2
Answer:
Area of the circle is 1764p cm^2
I have recently faced lot of problem while learning Mixed Numbers to Improper Fractions, But thank to online resources of math which helped me to learn myself easily on net.
