Question

hat is its side in terms of
in terms of x and
1.
A square field has an area expressed as 16x?- 8xy + 2
y? If x = 1 and y = 2, what is its side in metres?​

Answer 1

Answer:

2 metres

Step-by-step explanation:

1. area= 16 x^2 - 8xy + 2y
2. Putting x = 1, y = 2, we get
3. area = 16(1^2) - 8 (1)(2) + 2(2)
4. area = 16 - 16 + 4 = 4

since it is a square field

thus side =√area = √4 = 2

side of the field is 2 metres
