The perimeter is the sum of all a shapes sides.
so if length is two times the width, you could write it as 2w.
2w + 2w + w + w = 42. Simplified, it's 6w = 42.
Divide both sides by 6, and you get w = 7.
Since the length is 2w, 2 * 7 = 14, so the length is 14
Area of rectangle is length * width, so do 14 * 7 which is 98. Slap on some units and your answer is 98 sq m

Answer:
x= 32 ± √29
Step-by-step explanation:
x² - 8x - 13 = 0
ax² + bx + c = 0
Comparing equations we get,
a=1
b=(-8)
c=(-13)
Using quadratic formula,
________
x= b² ± √ b²-4ac
—————————
2a
Substituting the values
__________
x= 64 ± √( 64 + 52)
______________
2
= 32 ± √29

Answer:
1. d = -6 2. n = -80
Step-by-step explanation:
If you divide 42 by -252 you get -6. And if you use your mental math you see that two negatives make a positive then you see it has to be negative and 80/4= 20 than -80/-4 = 20. Hope this helps, let me know if correct, and have a great day!!
