Answer:
Length = 21
Width = 16
Step-by-step explanation:
We know that the formula for perimeter is:
P=2W+2L
And we also know that:
L=W+5
So then we put all that we know in the formula:
74=2W+2(W+5)
Now we expand the brackets and do some algebra:
74=4W+10 (-10)
64=4W (÷4)
16=W
Now that we know the width we can pop that into the length equation:
L=16+5
L=21
810+189-715= 284. the answer is 284
<h3>One possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively</h3><h3>Other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively</h3>
<em><u>Solution:</u></em>
<em><u>The volume of rectangular pyramid is given as:</u></em>

Given that,
<em><u>Rectangular pyramid has a volume of 190 cubic centimeters</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>Substitute, base area = 570 and height = 1</u></em>
Then we get,

Thus one possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively
<em><u>Substitute, base area = 285 and height = 2</u></em>

Thus other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively
