Question

The width of a rectangle is 1.9 feet. The perimeter is 7.4 feet. What is the length?

Answer 1

1.8 feet

Explanation:

This is the answer because:

Perimeter = L + W + L + W

1) Since we know the width of the rectangle is 1.9 feet, let's add 1.9 + 1.9 which is 3.8

2) Now, we know the total perimeter is 7.4, therefore, subtract 7.4 - 3.8 which is 3.6

3) Next, divide 3.6/2 which is 1.8

4) Finally, you can check your work by adding 1.8 + 1.8 + 1.9 + 1.9 which equals 7.4

Hope this helps!
