What is the area for this question?

Height of the figure is 12 ft.

Solution:

In this image parallel sides and area are given but height is not given.

We have to find the height of the figure.

Given image is a trapezoid.

Parallel sides = 4.2 ft and 9 ft

Area = 79.2 ft²

Area of the trapezoid =

79.2 = 6.6 × h

Divide by 6.6 on both sides, we get

12  =  h

Switch the sides of the equation.

h = 12

Height of the figure is 12 ft.

ik how do do this just give me a few minutes and i will give it to

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
