Answer:
15m
Step-by-step explanation:
Well, this can be shown using an equation:
2x- 12 = equation for width
x = equation for length
The area for a rectangle is width x length so:
(2x - 12) * x = 270
Make the equation a quadratic:
2x² - 12x - 270 = 0
(÷2) = x² - 6x - 135
Now you need to find what values multiply to -135 and add to -6, in this case it is +9 and -15
(x + 9)(x - 15)
So x = -9 and x = 15
<h3>The length has to be 15 because the length cannot be a negative, so the length of the rectangle is 15m!</h3>length = 3234 m and width = 1614 m
let the width = w then length = 2w + 6
Perimeter = 2 ( length + width )
= 2 (2w + 6 + w ) = 2 ( 3w + 6 ) = 6w + 12
given perimeter = 9696 the equating gives
6w + 12 = 9696
subtract 12 from both sides
6w = 9696 - 12 = 9684
divide both sides by 6
w = = 1614
width = 1614 m and length = (2 × 1614 ) + 6 = 3234 m
Answer: 217.6
Step-by-step explanation:
64% is a fraction of 100, so it would be 64/100.
Multiply that by 340.
You can also do 340 * 0.64 for the same result.
