Shape Area Calculator
Complete Guide to AI Area Calculator Tool
What is Area and Why is It Important?
Area is the measure of the extent of a two-dimensional surface or shape in a plane. Imagine painting a wall — the amount of paint needed depends on the area of the wall. Area is the two-dimensional equivalent of length for one-dimensional objects and volume for three-dimensional ones.
Standard Unit of Area:
- The International System of Units (SI) measures area in square meters (m²).
Our Ai area calculation tool makes it simple and fast to find the area of various shapes like rectangles, triangles, trapezoids, and circles. Let’s explore how it works and why it’s the best choice.

Our tool supports multiple shapes with easy-to-understand formulas and step-by-step calculations.
Shapes Supported and Their Area Formulas
1. Rectangle
A rectangle is a four-sided shape with opposite sides equal and four right angles.

Formula:
Area = Length × Width
Example: A plot of land measures 220 feet in length and 99 feet in width.
Area = 220 × 99 = 21,780 sq ft
2. Triangle
A triangle has three sides and three angles. We use Heron’s Formula when all three sides are known.

Formula:
s = (x + y + z) / 2
Area = √s(s - x)(s - y)(s - z)
Where:
x
,y
,z
= sides of the triangles
= semi-perimeter
Example: For a triangle with sides of 77 ft each:
s = (77 + 77 + 77) / 2 = 115.5
Area = √115.5(115.5 - 77)(115.5 - 77)(115.5 - 77) = 2,567.33 sq ft
3. Trapezoid
A trapezoid has one pair of parallel sides.

Formula:
Area = (b1 + b2) / 2 × h
Where:
b1
,b2
= parallel basesh
= height
Example: With bases of 9 ft and 29.528 ft and a height of 9 ft:
Area = (9 + 29.528) / 2 × 9 = 173.376 sq ft
4. Circle
A circle is a round shape defined by its radius.

Formula:
Area = πr²
Where:
r
= radiusπ
= 3.14159
Example: For a circle with a radius of 7 ft:
Area = π × 7² = 3.14159 × 49 = 153.94 sq ft
5. Parallelogram
A parallelogram is a four-sided shape with opposite sides parallel and equal.

Formula:
Area = Base × Height
Example: For a parallelogram with a base of 12 ft and a height of 8 ft:
Area = 12 × 8 = 96 sq ft
Important Terms, Area and shape:
Shape | Area | Terms |
Circle | π × r2 | r = radius of the circle |
Triangle | ½ × b × h | b = baseh = height |
Square | a2 | a = length of side |
Rectangle | l × w | l = lengthw = width |
Parallelogram | b × h | b=baseh=vertical height |
Trapezium | ½(a+b) × h | a and b are the length of parallel sidesh = height |
Ellipse | πab | a = ½ minor axis b = ½ major axis |
