the width of a piece of rectangular land is 5m shorter rhan 1/3 of its length .find the width of the land if the length is 60m,1

aniked [119]

Answer:

If width = 60 m, length = 195 m.

If width = 150 m, length = 465 m.

Step-by-step explanation:

The area of a rectangle is l * w or length times width.

So we can set an equation (letting w = width and x = length)

w = $1/3x - 5$

Part 1: width = 60m:

60 = $1/3x - 5$

65 = $1/3x$

x = 195 m

Part 2: width = 150 m:

150 = $1/3x - 5$

155 = $1/3x$

x = 465 m

Divide by 5 each side
X+2=4
Subtract 2 from each side
X=2

5(2+2)=20
Does work

In algebra when isolating (leaving alone on one side) x, you do the opposite operation, thus multiplying when you are trying to get rid of a division and vice versa
