The length of a rectangle is 7 meters more than four times its width if the area of the rectangle is 650 square meters, find the
length and the width. round to nearest tenth
1 answer:
Let the width be x.
Width = x
Length = 4x + 7
The area is 650 m²
x(4x + 7) = 650
4x² + 7x - 650 = 0
Using quadratic formula:
a = 4, b = 7, c = -650
Width = 11.9m
Length = 4(11.9) + 7 = 54.6m
Answer: Length = 54.6m and width = 11.9m
