Question

The area of a rectangle is 13.02 square feet. The width is 4.2 feet. What is the length?

Answer 1

`\boxed{\sf Length \ of \ rectangle = 3.1 \: feet}`

Given:

Area of rectangle = 13.02 square feet

Width of rectangle = 4.2 feet

To Find:

Length of rectangle

Explanation:

`\sf \implies Area \ of \ rectangle = Width * Length \\ \\ \sf \implies 13.02 = 4.2 * Length \\ \\ \sf \implies (13.02)/(4.2) = \frac{ \cancel{4.2}}{ \cancel{4.2}} * Length \\ \\ \sf \implies (13.02)/(4.2) = Length \\ \\ \sf \implies Length = (13.02)/(4.2) \\ \\ \sf \implies Length = \frac{3.1 * \cancel{4.2}}{ \cancel{4.2}} \\ \\ \sf \implies Length = 3.1 \: feet`

Answer 2

`\boxed{Length = 3.1 ft}`

Explanation:

Area of rectangle = Length * Width

For length, it'll be:

Length = Area/Width

Where Area = 12.02 ft^2, Width = 4.2 ft

Length = 13.02 / 4.2

Length = 3.1 ft
