The dimensions of the rectangular base will be 110ft by 330ft the length of the base measures less than 3 times the width
The formula for calculating the perimeter of the rectangular base is expressed as:
P = 2(L +W) where;
L is the length
W is the width
If the length of the base measures less than 3 times the width, then L < 3W
Given that Perimeter = 880feet
Substitute the given value into the formula to get the length
880 = 2(3W+W)
880 = 2(4W)
880 = 8W
W = 880/8
W = 110ft
Since L = 3W
L = 3(110)
L = 330ft
Hence the dimensions of the base will be 110ft by 330ft

The second one. It cancels out one but leaves one coefficient left which you divide and get the answer of x=0
Answer:
1728ft³
Step-by-step explanation:
Split the shape into the two rectangular prism that make it up
Volume of a rectangular prism=length*width*height
Small prism=10*12*3=360ft³
Big prism=19*12*6=1368ft³
Total=360ft³+1368ft³=1728ft³
