Answer:
1 . 24
2. 21
Step-by-step explanation:
1.
b=6
h=4
A= b*h
=6*4
=24
2. b=6
h= 7
A= 1/2*b*h
= 1/2*6*7
=21

None of the numbers repeat unlike the other decimals
Answer:
33/7
Step-by-step explanation:
Let x be the width of the cardboard (which means the length of the cardboard is x+88), then the dimensions of the box are:
Length = [(x + 88) - 2(33)]
Width = x - 2(33)
Heighth = 33
Volume = length · width · heighth
144,144 = [(x + 88) - 2(33)] · [x - 2(33)] · 33
144,144 = (x+22)(x-66)(33)
4368 = (x+22)(x-66)
4368 = x² - 44x - 1452
0 = x² - 44x - 5820
use the quadratic formula to calculate that x = 101
Answer: cardboard width = 101, cardboard length = 189
