Question

Can I have help with this question? Find the perimeter of the parallelogram. (7/8x+2/9y)cm (10-x+4/9y)

Answer 1

The perimeter of the parallelogram can be calculataed as,

`P=2(a+b)`

Here,

`\begin{gathered} a=10-x+(4)/(9)y \\ b=(7)/(8)x+(2)/(9)y \end{gathered}`

Therefore,

`\begin{gathered} P=2(10-x+(4)/(9)y+(7)/(8)x+(2)/(9)y) \\ =2((-1+(7)/(8))x+(7)/(9)y) \\ =-(1)/(4)x+(14)/(9)y \end{gathered}`
