Pls i dont know whether to use 6, 10, or 16 as a side length

d = 19

Step-by-step explanation:

First, you need to find the length of the diagonal of the rectangular base of the prism. It's the dashed segment on the base of the prism.

The base of the prism is a rectangle with sides 10 and 6. We can use the Pythagorean theorem to find the diagonal.

10^2 + 6^2 = x^2

100 + 36 = x^2

x^2 = 136

x = sqrt(136)

The dashed diagonal of the rectangular base has length sqrt(136).

Now you use the dashed diagonal and the vertical side measuring 15 as the legs of another right triangle. The diagonal labeled d is the hypotenuse of this triangle. We use the Pythagorean theorem again.

15^2 + (sqrt(136))^2 = d^2

225 + 136 = d^2

d^2 = 361

d = 19

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

only 10/60 isn't equivalent

hope this : )
