Question

The area of a rectangle is 30ft^2. How long is the width if the length is 5 feet.

Answer 1

Width = 6ft

Explanation:

The area formula for rectangles is A=L×W, where A is the area, L is the length, and W is the width.

So far, we know that A=30ft² and L=5ft.

Plug them into our area formula:

30ft² = W × 5ft

Solve for W. ÷ 5ft both sides.

30ft²/5ft = W

W = 6ft

Width = 6ft

Answer 2

Answer: 6 feet

Area of a rectangle formula: A=lw

Plug in the numbers you know.

30=5w

Then solve it like a normal equation.

30=5w

30/5=5w/5

6=w
