# Area Of 2D Figures

### Area of Triangle

Area = base height The base and height of triangle should be perpendicular to each other.

Example: Find the area of triangle with base length 4 ft and vertical height 3 ft.

### Area of Square

Area of a square = (side)2 Example: What is the area of square with each side length 2 yards?

Area of a square = (side)2 = (2)2 = 4 yd2

### Area of Rectangle

Area of a rectangle = length × width  Example: What is the area of a rectangular sheet with length 8 inches and width 4 inches?

### Area of Parallelogram

Opposite sides in parallelogram are equal in length and opposite angles are equal in measure.

Area of parallelogram = base × height

Example: What is the area of given parallelogram? Area of parallelogram = base × height = 4 mi × 3 mi = 12 mi2

### Area of Trapezoid

A trapezoid has one pair of sides that are parallel to each other.

In the figure below, base 1 and base 2 are parallel to each other. Area of trapezoid = (base 1+base 2) height

Example: Find the area of a trapezoid with bases 7 cm and 3 cm. The height of trapezoid is 4 cm.

#### Check Point

1. ABC is a right angled triangle with hypotenuse AC = 25 cm and base, BC = 24 cm. Find the area of triangle ABC.
2. Find the area of a square field which is double the area of a rectangular field with length 60 m and 40 m.
3. If the diagonal of a square is in, what is the area of square?
4. What is the area of a trapezoid with height 3 in, and bases 1.5 in and 6.5 in?
5. Find the area of parallelogram with base 7.5 yd and height 6.8 yd.
