Question

i need help to get the answers to these 3 questions

Answer 1

Here is the anwer:-
Let length of garden = x
and breadth of garden = (180-x)
1. area= x*(180-x)= 180x-x^2 ft^2
2. dimensions for greatest area will be
length = 90/2 feet= 45 ft.
breadth= 180-90 = 90/2 ft. = 45ft.
3. greatest area(from 2) = 45*45 = 2025 ft^2

WE DIVIDED BY 2 bcz perimeter is 2(x+y) where y = 180-x
