# Find the area and perimeter of right triangle in PL/SQL

• Last Updated : 02 Jul, 2018

Prerequisite PL/SQL introduction

In PL/SQL code groups of commands are arranged within a block. A block group related declarations or statements. In declare part, we declare variables and between begin and end part, we perform the operations.

Given the lengths of hypotenuse, base, and height of a right triangle, the task is to find the area and perimeter of the triangle.

Examples:

```Input: hypotenuse = 10, base = 4, height = 14
Output:  Area = 28, Perimeter = 28
Input: hypotenuse = 30,  base = 10, height = 25
Output: Area = 125, Perimeter = 65
```

Formula for calculating area and perimeter:
Area of right triangle:

` 1/2 * base * height`

Perimeter of triangle:

`len of hypotenuse + len of base + len of height`

Below is the required implementation:

 `DECLARE``    ``-- declare variable side1, side2,``    ``-- base, height, area and perimeter``    ``-- and these six variable datatype``    ``-- are float``    ``hypotenuse     ``FLOAT``;``    ``base      ``FLOAT``;``    ``height    ``FLOAT``;``    ``area      ``FLOAT``;``    ``perimeter ``FLOAT``;``BEGIN``    ``-- here we assign the value in``    ``-- side1, side2, base, height  ``    ``hypotenuse := 10;`` ` `    ``base := 4;`` ` `    ``height := 14;`` ` `    ``area := .5 * base * height;`` ` `    ``perimeter := hypotenuse + height + base;`` ` `    ``dbms_output.Put_line(``' Area of triangle is '``                         ``|| area);`` ` `    ``dbms_output.Put_line(``' Perimeter of triangle is '``                         ``|| perimeter);``END``;``-- Program End `

Output :

``` Area of triangle is 28
Perimeter of triangle is 28
```
