Question

PLZ HURRY IT'S URGENT!!

The length of a rectangle is 4 inches longer than its width. The area of the rectangle is 12 square inches. What are the length and width?

Which equation models this problem?


w – (4 + w) = 12


w + (4 + w) = 12


w(4 + w) = 12


4 • w = 12

Answer 1

The answer is w(4+w)=12

Explanation:

Answer 2

The equation that models this problem is w(4 + w) = 12

Explanation:

we know that

The area of a rectangle is

`A=LW`

we have

`A=12\ in^2`

so

`12=LW` -----> equation A

`L=W+4` ----> equation B

substitute equation B in equation A and solve for W

`12=(W+4)W`

therefore

The equation that models this problem is w(4 + w) = 12
