Question

A bedroom has a length of x+ 3 feet and a with of x feet find the area when x =10

Answer 1

Length: 13ft

Width: 10ft

Explanation:

Length: x+3

Width: x

X= 10

Length: 10 + 3 = 13ft

Width: 10ft

Answer 2

Answer: 130 square feet.

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 :-

`A(x)=\text{Length}*\text{Width}\\\\\Rightarrow\ A(x)=(x+3)*(x)`

At x= 10

`A(x)=(10+3)*(10)=130\ \text{square feet.}`

Hence, the area when x =10 is 130 square feet.
