Answer:
Therefore,


Step-by-step explanation:
Let the Width of rectangle be 'x' cm.
Then the length of a rectangle will be (x + 5) cm.
Area of rectangle given is 84 cm squared.
To Find:
Length = (x+5) = ?
Width = x = ?
Solution:
We have area of rectangle given as

Substituting the given values we get

On factorizing we get

Therefore,

Therefore,


The algebraic expressions would be a÷9
Answer:


Step-by-step explanation:
Lets call

equation 1

equation 2
using equation 2, we would make y the subject of the formula as it would be easier

This would now be called our equation 3
Now the next step is to substitute equation 3 in equation 1





Divide both sides by 27

Substitute the value of x in equation 2
