Question

a rectangle has a width of 10 and a length of 4. find its area.

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 $l = 4$ and $w = 10$, we substitute into the formula: $A=4\times10$.

Step3: Calculate result

$4\times10 = 40$.

Answer:

40
