What are the equations to find the area of a rectangle, square, trapezoid, and triangle?

The equations to find the area of a rectangle are: multiply the length by the width A = lw

The equations to find the area of a square are: multiply the length by the width A = lw

The equations to find the area of a trapezoid are: multiply the sum of the upper base and lower base by the height  and then divide by 2. A =  

The equations to find the area of a triangle are: multiply the base by the height, then multiply by 1/2. A = bh × 1/2

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
