Question

What is the approximate length of one side of Kesiah's kitchen, which is shaped like a square and has an area of 240 ft²?

A) 12 ft
B) 15 ft
C) 20 ft
D) 30 ft

Answer 1

The approximate length of one side of Kesiah's square kitchen with an area of 240 ft² is found by taking the square root of 240, which is approximately 15 ft, therefore the answer is B) 15 ft.

Step-by-step explanation:

To find the approximate length of one side of Kesiah's square kitchen with an area of 240 ft², we need to take the square root of the area because the formula for the area of a square is ² = side length × side length. Thus, the side length is the square root of the area.

Calculating the square root of 240, we get:√240 ≈ 15.49 ft. Therefore, the closest approximate length of one side of the kitchen is 15 ft.

Answer: B) 15 ft
