If you would like to solve 26/57 = 849/5x, you can do this using the following steps:

26/57 = 849/5x /*(5x)
26/57 * (5x) = 849 /*57
26 * 5x = 849 * 57 /26
5x = 48393/26 /5
x = 48393/(26*5)
x = 372.25

The correct result would be 372.25.

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a single-strand electric

Answer:

dimension are 350 m and 350 m and

area is 122500 m²

Step-by-step explanation:

Given data

perimeter is 700 m

to find out

the largest area and its dimensions

solution

we consider x and y are the sides

so area is xy

perimeter is 2x+ y = 700

so we can say y = 700 -2x

so area will be = x (700 - 2x)

area = 700x - 2x²

we take derivative here and equal to zero

dA/dt = 700x - 2x²

700 - 4x = 0

x = 700/4

x = 175

so will be

y = 700 -2x

y = 700 -2(175)

y = 350

so dimension are 350 m and 350m

area is 122500 m²
