Find the area of the rectangle with the given base and height.
gulaghasi [49]

Answer: Area = 108 in. or 3/4 ft.

Step-by-step explanation: The formula for the area of a rectangle is l•w (length times width).

To get the area, you need to convert the units of measurement to one or the other (either inches or feet) because you cannot multiply them unless they are the same.

To get the area in inches, you convert 3 ft. to inches which is 36 inches, and then multiply it by 3 inches. You will get that the area = 108 inches.

To get the area in feet, you convert 3 inches to feet which is 1/4 (or 0.25) feet and then multiply it by 3 feet which gives you area = 3/4 ft. (or 0.75 ft.). Hope this helps.

Solve for the distance between (13,55) and (61,22). Round your answer to the nearest hundredth.​
Neporo4naja [7]

Answer:

Step-by-step explanation:

position 1: (13,55)

position 2: (61,22)

distance = \sqrt{(p_{x2}-p_{x1})^{2} + (p_{y2}-p_{y1} )^{2}}

distance = \sqrt{(61-13)^{2} + (22-55)^{2}}

distance = \sqrt{(48^{2} + (-33)^{2} }

distance = \sqrt{2304 + 1089}

distance = \sqrt{3393}

distance = 58.25

There should have been an attached image.

Area of a circle is can only be computed when the radius or diameter is provided.

Area of a circle = π r²

Based on the image I saw, the radius is 5.6 inches

A = 3.14 * (5.6in)²
A = 3.14 * 31.36 in²
A = 98.47 in² ⇒ CHOICE D. 98.5 square inches.
