The length of a rectangle is five times its width.

Mathematics
1 answer:
Marizza181 [45]3 years ago
5 0

ANSWER

96 yd

EXPLANATION

Let the width of the rectangle be w, then, the length of the rectangle will be:

l = 5w

The area of a rectangle is calculated using the formula:

Area=l \times w

Area=5w \times w

Area=5 {w}^{2}

It was given that, the area of the rectangle is 320yd²

320=5 {w}^{2}

Divide both sides by 5.

64 =  {w}^{2}

Take square root of both sides to get:

w = 8yd

This means the length is

l = 5 \times 8 = 40yd

The perimeter of a rectangle is given by:

P=2(w+l)

We plug in the values to get:

P=2(40 + 8) = 2 \times 48 = 96yd

The perimeter is 96yd

The projected T. rex is about
dolphi86 [110]

Answer: scale\ factor=230

Step-by-step explanation:

You need to analize all the information given in the exercise.

You know that the actual height of the T-rex on the projector lens is the following:

actual\ height=2\ cm

The height of the projected T-rex is:

projected\ height=4.6\ m

Make the conversion from meters to centimeters:

projected\ heigth=(4.6\ m)(\frac{100\ cm}{1\ m})\\\\projected\ heigth= 460\ cm

Therefore, the scale factor will be:

scale\ factor=\frac{projected\ heigth}{actual\ heigth}

Finally, you must substitute values into the equation and then you must evaluate in order to find the scale factor of the projection. You get that this is:

scale\ factor=\frac{460\ cm}{2\ cm}\\\\scale\ factor=230
