Problema Solution

In a rectangle, the diagonal measures p

130 inches. The length of the rectangle is two inches more

than three times the width. Find the AREA of this rectangle.

Answer provided by our tutors

let


l = length of the rectangle

w = width of the rectangle

d = 130 diagonal


the length of the rectangle is two inches more than three times the width


l = 2 + 3w


by Pythagorean Theorem


w^2 + l^2 = d^2


w^2 + l^2 = 130^2


by solving the system of equations


l = 2 + 3w

w^2 + l^2 = 130^2


we find


l = 123.53 in


w = 40.51 in


the area = width * length


the area = 123.53 * 40.51 = 5004.2 in^2.
