the length of a rectangle is equal to triple the width. if the perimeter is equal to 168 feet ,what is the length of the rectang
Leokris [45]

Answer:

The length of the rectangle = 63 ft

Step-by-step explanation:

Let us assume the width of the rectangle  = m ft

So, the length of the rectangle  = 3 x Width = 3 x  m = 3 m ft

Perimeter = 168 ft

PERIMETER OF A RECTANGLE = 2 (LENGTH + WIDTH)

⇒ 168 ft = 2 ( 3 m + m)

or, 168 = 2 ( 4 m)

or, 8 m =  168

⇒ m = 168/8 = 21

or, m = 21  ft

Hence, the width of the rectangle  = m = 21 ft

And the length of the rectangle = 3 x m  = 3 x 21   = 63 ft

Juanita bought a square calculator that has a measurement of 8.2 sq cm on one side. What is the area of the calculator?
Sunny_sXe [5.5K]
Since all sides of a square are the same you can square the side length you are given.
A = (8.2)x(8.2) or 8.2^2
That would give you 67.24

A bridge is built in the shape of a semielliptical arch. It has a span of 112 feet. The height of the arch 26 feet from the cent
katen-ka-za [31]
Solve this using standard form of ellipse equation: <span>(x−h<span>)^2</span>/<span>a^2</span>+(y−k<span>)^2</span>/<span>b^2</span>=1.

</span><span>Put the center of the ellipse at (0,0), then h=k=0, so that simplifies things. If the span is 112 feet, then the semi-major axis in the x direction is 56, that would be 'a' I think you have to use the given information to solve for 'b.'

</span><span>Getting 13.5488, so 13.5 or 13.55 feet seems fine as a rounded answer.</span>
