Question

1. the length of a rectangle is 2.1 feet. the width of the same rectangle is 1.8 feet. find the area in square feet.

Explanation:

Step1: Recall area formula

The area formula for a rectangle is $A = l\times w$, where $l$ is the length and $w$ is the width.

Step2: Substitute values

Given $l = 2.1$ feet and $w = 1.8$ feet, we substitute into the formula: $A=2.1\times1.8$.

Step3: Calculate result

$2.1\times1.8 = 3.78$ square - feet.

Answer:

$3.78$ square feet
