Question

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

Answer 1

Answer:

3.1

Step-by-step explanation:

Since this is area and you are given the width must divide area by width ( A/W = L) 13.02 divided by 4.2 = 3.1. You can check this by doing 3.1 multiplied by 4.2. It should give you 13.02

Answer 2

The length of the rectangle is 3.1 feet.

SOLUTION:

Given that, the area of a rectangular painting is 13.02 square feet.  The width is 4.2 feet.  

We have to find the length. Now, we know that, area of the rectangle is the product of its length and breadth i.e.

$\bold{\text{area of the rectangle} = l\times b}$

where l is the length of the rectangle and b is breadth of the rectangle.

Here, area = 13.02 square feet; b = 4.2 feet  

On substituting in the formula we get,

$\bold{13.02=l\times 4.2 \rightarrow l=\frac{13.02}{4.2} \rightarrow l=3.1}$

Hence, the length is 3.1 feet.
