Solve the area of a trapezoid formula for the variable h: A = 1/2h(b1 + b2)
Note: In this formula, A = area, H = height, and b1 and b2 are the bases of the trapezoid.

The area of the trapezoid formula can be solved for the variable h as,

h = 2A / (b1 + b2)

Given the formula to find the area of the trapezoid.

A = 1/2 (b1 + b2) h

Here A is the area, h is the height and b1 and b2 are the bases of the trapezoid.

We have to get an equation for formula in h.

That is, we need to isolate h alone on one side and the other terms and variables on other side.

Multiplying whole equation with 2,

2A = (b1 + b2) h

Dividing whole by (b1 + b2),

h = 2A / (b1 + b2)

Hence the required equation is h = 2A / (b1 + b2).

A study gathers data on the outside temperature during the winter, in degrees Fahrenheit, and the amount of natural gas a household consumes, in cubic feet per day. Call the temperature x and gas consumption y. The house is heated with gas, so x helps explain y. The least-squares regression line is yhat = 1344 – 19x. 1. On a day when the temperature is 20F, the regression line predicts that gas used will be about
