Question

In rectangle klmn km=7x+20 and ln=55. what is the value of x

Answer 1

Start by drawing the rectangle and naming the corners and distributing the corresponding distances

Since we are talking about a rectangle sides KM and LN are the same, which gives the following equation

`7x+20=55`

solve the equation for x

`\begin{gathered} 7x=55-20 \\ 7x=35 \\ x=(35)/(7) \\ x=5 \end{gathered}`

The value of x is 5.
