Problem 1

A rectangular field has a length of 23 meters and a width that is the square of -23. What is the area of the field?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The area of a rectangle = length × width

 

Length = 23 meters

 

Width = square of -23 = 529 meters

 

Area = 23 × 529 = 12,167 square meters

Explanation

The width of the field is the square of -23, which is 529 meters. Multiplying the length by the width gives the area, which is 12,167 square meters.

Problem 2

A car travels a distance equal to the square of -23 kilometers in 2 hours. What is the average speed of the car?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Distance traveled = square of -23 km = 529 km

 

Time = 2 hours

 

Average speed = distance/time = 529 km / 2 hours = 264.5 km/h

Explanation

The car travels 529 kilometers in 2 hours, resulting in an average speed of 264.5 km/h.

Problem 3

A circular garden has a radius that is the square of -23. Find the circumference of the garden.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The radius of the garden = 529 meters

 

Circumference of the circle = 2πr

 

Circumference = 2 × 3.14 × 529 = 3,322.12 meters

Explanation

The radius is 529 meters, and using the formula for circumference, 2πr, the circumference is calculated as 3,322.12 meters.

Problem 4

The area of a square plot is 529 square meters. Find the length of each side of the plot.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The area of the square = a²

 

So, the area is 529 square meters

 

The length of each side = √529 = 23 meters

Explanation

Since the area of the square is 529 square meters, taking the square root gives each side as 23 meters.
