Question

emily wants to buy a tablecloth to cover a square card table. she knows the tabletop has an area of 9 square feet. what are the minimum dimensions of the tablecloth emily needs? emily should buy a tablecloth that measures at least feet by feet. √9 = √3·3 9 = 3²

Explanation:

Step1: Recall area formula for square

The area formula for a square is $A = s^2$, where $A$ is the area and $s$ is the side - length.

Step2: Solve for side - length

Given $A = 9$ square feet, we need to find $s$. Rearranging the formula gives $s=\sqrt{A}$. Substituting $A = 9$ into the formula, we have $s=\sqrt{9}=3$ feet. Since it's a square table, the minimum dimensions of the tablecloth (which also should be at least as big as the tabletop) are 3 feet by 3 feet.

Answer:

3 feet by 3 feet
