Following program shows you how to calculate trapezoid area.
This program gets trapezoid base and height from user and calculates area and prints it using following formula
Area = (base1 + base2) X height /2

#include <stdio.h>

int main(void) {
    float trapezoidBase1;
    float trapezoidBase2;
    float trapezoidHeight;

    printf("Please enter base1 of trapezoid:");
    scanf("%f", &trapezoidBase1);

    printf("Please enter base2 of trapezoid:");
    scanf("%f", &trapezoidBase2);

    printf("Please enter height of trapezoid:");
    scanf("%f", &trapezoidHeight);

    float areaOfTrapezoid =
        (trapezoidBase1 + trapezoidBase2) * trapezoidHeight / 2;

    printf("Area of trapezoid is: %f", areaOfTrapezoid);


Please enter base1 of trapezoid: 13
Please enter base2 of trapezoid: 15
Please enter height of trapezoid: 20
Area of trapezoid is: 280.000000
