I’m not 100% sure but isn’t it x2 +xy +y2?
Answer:56.8 inches
Step-by-step explanation:
For perimeter we must find the lengths of the 2 diagonal sides of the triangle which are the same because it is isosceles.
the triangle is cut directly in half so both halves of the base are 17/2
17/2 = 8.5
solve through pythagoren theorum
altitude^2 + (half of base)^2 = (diagonal length)^2
18^2 + (8.5)^2 = (diagonal length)^2
324 + 72.25 = (diagonal length)^2
396.3 = (diagonal length)^2
= diagonal length
diagonal length = 19.9
diagonal length + diagonal length + base = perimeter
19.9 + 19.9 + 17 = perimeter
56.8 inches = perimeter
Answer: 100 square units.
Step-by-step explanation:
Given: Jernel has to figure out the area of her square garage.
She knows that one side of the garage is equal to the length of her rabbit pen.
Now, the length of the rabbit pen = 10 units
Then , the length of the garage will be 10 units
Now, Area of square = 
Hence, the area of the garage = 100 square units.
