Answer:
Step-by-step explanation:
The side length of a square is 1/4 of the perimeter, so the side length of the square orchard is (1600 m)/4 = 400 m.
The area of a square is the square of the side length, so the area of the orchard is (400 m)² = 160,000 m².
A hectare is 10,000 m², so the area of the orchard in hectares is ...
16·(10,000 m²) = 16 ha
Answer:
I'd say half
Step-by-step explanation:
<span>x^2+15=8x
</span><span>x^2-8x=-15
x^2 - 2 (x)(4) =-15
adding 16 on both sides
</span>x^2 - 2 (x)(4) +16=-15+16
x^2 - 2 (x)(4) + 4^2= 1
(x-4)^2=1
taking square root on bothsides x-4 = +-1
so x-4=1 or x-4=-1
x-5 or x=3
Each side is 5 inches long. This is because a square has 4 sides, so 20 ÷ 4 =5
