Arectangular area has dimensions 432 feet by 345 feet. using front-end estimation on the dimensions, what is an estimate of the amount of fencing required to enclose the rectangular area? a. 1200 ft. b. 1300 ft. c. 1400 ft. d. 1600 ft.

Option C. 1400 ft

Step-by-step explanation:

we know that

In a Front End Estimation we keep only one number in the front and all the others became zeros

The perimeter of a rectangular area is equal to

where

L is the length and W is the width

we have

Applying front-end estimation

we have

Find the perimeter

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
