Length: x+3
Width: x
X= 10
Length: 10 + 3 = 13ft
Width: 10ft
Answer: 130 square feet.
Step-by-step explanation:
We assume that the shape of bedroom is rectangular.
Given : A bedroom has a length of x+ 3 feet and a with of x .
Then, the area of bedroom is given by :-
[tex]A(x)=\text{Length}\times\text{Width}\\\\\Rightarrow\ A(x)=(x+3)\times(x)[/tex]
At x= 10
[tex]A(x)=(10+3)\times(10)=130\ \text{square feet.}[/tex]
Hence, the area when x =10 is 130 square feet.
