Question

The area of a rectangle is 133 square centimeters. If the perimeter is 52 centimeters, find the length and width of rectangle.

Answer 1

xy = 133 --(1)
2(x+y)=52 --(2)
from (1),
x=133/y
sub this into (2)
2(133/y +y)=52
133/y +y =26
133 + y^2 = 26y
y^2 -26y -133=0 <-- solve by quadratic formula or calculator
solve this and then put y into x=133/y to find x

Answer 2

y = {30.378147197, -4.378147197}

Answer 4

The length is 7 and the width is 19
