What is the distance between points A and B shown in the graph below
Bas_tet [7]

Answer:

D = 7\sqrt 2

Step-by-step explanation:

Given

A = (-3,-4)

B = (4,3)

Required

The distance between them

This is calculated as:

D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

So, we have:

D = \sqrt{(3-(-4))^2+(4-(-3))^2}

D = \sqrt{7^2+7^2}

D = \sqrt{2(7^2)}

D = 7\sqrt 2

Answer:

  • figure the areas of the rectangle and semicircle
  • add them together

Step-by-step explanation:

The area of the rectangle is given by ...

  A = LW

  A = (20 m)(14 m) = 280 m²

__

The area of the semicircle is ...

  A = (1/2)πr²

  A = (1/2)π(7 m)² = 24.5π m² ≈ 77 m²

__

Then the total area is ...

  280 m² +77 m² = 357 m²

_____

The width of the rectangle is the diameter of the circle, which is twice its radius. The area of a semicircle is 1/2 the area of a circle.
