How do u solve number 11

#11 is an isosceles triangle which means 2 sides are the same. If they give you the hypotenuse, then I'm assuming the 2 same sides are unknown.

Using the Pythagorean Theorem, a^2+b^2=c^2, then you get:

a²+b²=8²

a²+b²=64

Which means a² and b² must be 32 each because they are the same. Find the sqrt of 32 for the smaller legs.

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.'
