Answer:
C) 11, 700 yd²
Step-by-step explanation:
Let [tex]x[/tex] = width of a rectangle
Let [tex]y[/tex] = length of a rectangle
Area of a rectangle = width x length
⇒ area = [tex]xy[/tex]
If a rectangular garden has an area of 52 yd²
⇒ [tex]xy[/tex] = 52
If the length and width are multiplied by 15:
⇒ new width = [tex]15x[/tex]
⇒ new length = [tex]15y[/tex]
⇒ area = [tex]15x \times 15y=225xy[/tex]
If xy = 52,
new area = 225xy = 225 x 52 = 11700
