The width of a rectangle is 3 units less than the length. if the area is 130 square units, then find the dimensions of the rectangle.

Length = 10

Width = 13

Step-by-step explanation:

If the width of a rectangle is 3 units less than the length and if the area is 130 square units, the length is 10 units and the width is 13 units.

Formula: A=wl

Therefore, you have to find what two numbers multiply together in order to recieve 130 units.

A=wl=13·10=130

10 =

13 =

Step-by-step explanation:

= -3 +

[-3 + ] = 130 ↷

² - 3 - 130 ↷

[ + 10][ - 13] → [Notice that he negative symbol was not boldfaced because when we ate talking about dimensions, we want NON-NEGATIVE numbers.]

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
