Alot is in the shape of a trapezoid. the sum of the bases is 280 feet. if the area of the lot is 8,400 square feet, what is the distance across the lot, i. e., the altitude of the figure? the altitude of the trapezoid is feet.

The altitude of the trapezoid is 60 feet.

Step-by-step explanation:

Trapezoid

Sum of the bases: B+b=280 feet

Area of the trapezoid: A=8,400 feet^2

Altitude of the trapezoid: h=?

The formula to calculate the area of a Trapezoid is:

A = (1/2) (B+b) h

Replacing the given values:

8,400 feet^2 = (1/2) (280 feet) h

(1/2) (280 feet) = (140 feet)

8,400 feet^2 = (140 feet) h

Solving for h: Dividing both sides of the equation by 140 feet:

8,400 feet^2 / (140 feet) = (140 feet) h / (140 feet)

60 feet = h

h = 60 feet

The altitude of the trapezoid is 60 feet.

no this is a nonlinear negative
