<h3>hello!</h3>
You can use the acronym PEMDAS to help you remember the Order of Operations in Maths.
Here's what it stands for:-
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
According to PEMDAS, the first operation is:-
Option A) 19-4

Answer:
rectangle with maximum area has dimensions of 745 yd x 1490 yd
Step-by-step explanation:
the rectangular area is
Area = x*y , where x= side along the river , y = side perpendicular to the river
since we have only 2980 yd of fencing, the total fencing ( perimeter) will be
x+2*y = 2980 yd =a
then solving for x
x= a - 2*y
replacing in the area expression
A=Area = x*y = (a- 2*y) *y = a*y - 2*y²
the maximum area is found when the derivative with respect to y is 0 , then
dA/dy= a - 4*y = 0 → y=a/4 = 2980 yd /4 = 745 yd
then
x= a - 2*y = a - 2* a/4 = a/2 = 2980 yd /2 = 1490 yd
then the rectangle with maximum area has dimensions of 745 yd x 1490 yd
