A countertop is 11 feet long and 4 fee t wide.

What is the area of the countertop in square meters? Use the conversion 1 foot = 0.305 meter. Round your
final answer to 2 decimal place

Answers

Answer:

4.09m^2

Step-by-step explanation:

A countertop is 11 feet long and 4 fee t wide.

Using the conversion

1foot = 0.305 meter

11fet = 11(0.305)

11feet = 3.355 m

4 feet= 4 * 0.305

4feet = 1.22m

Area of the countertop = Length * Width

Area of the countertop = 3.355 * 1.22

Area of the countertop = 4.0931m^2

Hence the required area is 4.09m^2 to 2 decimal places

x ≈ 16.6 units

Step-by-step explanation:

The angle between a tangent and the radius at the point of contact is 90° , so

Δ ABC is a right triangle at ∠ B

Using Pythagoras' identity in the right triangle

x² + 7² = 18²

x² + 49 = 324 ( subtract 49 from both sides )

x² = 275 ( take the square root of both sides )

x = [tex]\sqrt{275}[/tex] ≈ 16.6 ( to the nearest tenth )
