Introduction to 4th grade math area:
Area is a quantity expressing the two-dimensional size of a defined part of a surface, typically a region bounded by a closed curve. The surface area of a 3-dimensional solid is the total area of the exposed surface, such as the sum of the areas of the exposed sides of a polyhedron. Area is an important invariant in the differential geometry of surfaces. In this article we shall discuss about 4th grade math area problem. (Source: Wikipedia)
4th grade math area example problem
Here we are going to discuss some 4th grade math area problems with detailed solutions.
Example 1:
Find the area of the rectangle, the rectangle base value 23m and height of rectangle is 10 m.
Solution:
Let base b = 23 and rectangle height h = 10.
Then the area of the rectangle formula = b × h
The area of the rectangle = 23 × 10
= 230 sq. meters.
Therefore the area of rectangle = 230 sq. meters.
Example 2:
Find the area of the circle, the circle radius value 12.
Solution:
Area of the circle formula = pi r2
Pi = 22/7 or 3.14
The area of the circle = 22/7× 12x12
= 452
Answer:
Therefore the area of circle = 452
Example 3:
Find the area of the square; the square one side of length value is 22units.
Solution:
Formula for finding area of square = a2 of (Side) 2
The side value of the area = 22
Therefore (22) 2
That is 22 * 22 = 484
Area of the square = 484units.
Example 4:
Find the area of triangle, the triangle base value=20cm and the height of the triangle = 12cm
Solution:
Area of the triangle formula = `1/2` b x h
Height of the triangle = 12
Base of the triangle = 20
Therefore area of triangle = `1/2` x 20 x 12
The area of triangle = 120cm
Example 5:
Find the area of the rectangle, the rectangle base value 22m and height of rectangle is 15 m.
Solution:
Let base b = 22 and rectangle height h = 15.
Then the area of the rectangle formula = b × h
The area of the rectangle = 22 × 15
= 330 sq. meters.
Therefore the area of rectangle = 330 sq. meters.
Understanding right triangle trigonometry is always challenging for me but thanks to all math help websites to help me out.

Base of the triangle = 20
Therefore area of triangle = `1/2` x 20 x 12
The area of triangle = 120cm
Example 5:
Find the area of the rectangle, the rectangle base value 22m and height of rectangle is 15 m.
Solution:
Let base b = 22 and rectangle height h = 15.
Then the area of the rectangle formula = b × h
The area of the rectangle = 22 × 15
= 330 sq. meters.
Therefore the area of rectangle = 330 sq. meters.
