Answer:
Width=37in
Length=55in
Step-by-step explanation:
Let x in be the width dimension, the length dimension will be x+18 in. Area of a rectangle is calculated as A=lw. Given the area as2143 sq in, x can be calculated as:

#Substitute for every x in our function to find the true value of x:
#l=37+18=55in
for x=38:
#l=38+18=56in
For x=39:
#l=39+1854in
From the calculations above, A television with a width of 37 in and length 55in has its area closest to 2143 sq in.

hello thanks for the f.r.e.e points saving
to give 100 Satep-by-step explanation:
this is an isosceles triangle... meaning that the two base angles will be equal.
180 - 38 = 142
142 / 2 = 71
x = 71
