The perimeter of a triangle has the formula 2l + 2w. Since the length is twice as long as the width, l = 2w. We use this equations to two possible perimeters, 90 and 120 feet.
P = 90 feet
90 = 2(2w) + 2w
90 = 6w
w = 15 feet
P = 120 feet
120 = 2(2w) + 2w
120 = 6w
w = 20
Thus, the range of w is from 15 to 20 feet. The answer is <span>15 ≤ w ≤ 20</span>
<em><u>Answer:</u></em>
12.8 or option 3
<em><u>Step-by-step explanation:</u></em>
So this is actually a proportion:
The large triangle to the smaller one:
<em>The angles of the triangles are the same so they are proportional</em>
We know the larger one is 20/8 times the smaller one's sides because
<em>YZ = something times QR so:</em>
20 = 8 times 20/8
In order to find PR, we have to divide ZX by the proportion rate thing so:
32 / (20/8)
= 32 * 8/20
= 64/5
= 12.8
Step-by-step explanation:
B. 20 only

Answer:
51 meters
Step-by-step explanation:
to solve scale multiply the scale measurement (3) by the drawing (17).
3 X 17 = 51 and make sure to use the correct unit (meters) that the drawing states.
