Need help figuring out my son's math homework?
Covering and Surrounding
Oliver drew a rectangle. He says the area of his rectangle is 7 square units and the perimeter is 16 units. Do you think Oliver is correct?
Explain.
Thank you that helps alot!
Would you figure out this one the same way?
Is it possible for a rectangle with an area of 42 square units to have a perimeter of 28 units?

i think oliver is correct
the area of a rectangle is base times height, so assuming that the base is 1 unit and the height is 7 units, then 7 x 1 = 7
the perimeter of the rectangles is adding up all sides so
7 + 7 + 1 + 1 = 16
hope that helped :)

Yes. The area is lenght x width. A rectangle 1 by 7 units: 1 x 7=7(area). 1+1+7+7=16(perimeter - number ouf units around the outside that form the shape)

Area of a rectacle is length of one side times the height of one side
Perimeter is addition of all sides.
So a rectangle that has a height of 7 and a length of 1 would fit this discription:
7 x 1 = 7 (area)
7 + 7 + 1 + 1 = 16 (perimeter)

Yes the rectangle is 7 units long 1 unit high. 7*1 =7 (Area) and 7+7+1+1 = 16 (perimeter)

yes i think oliver is correct.
It's a rectangle. If you had a 7^2 units area the rectange would have to look like this..
LLLLLLLI
((^^that is supposed to be a rectangle, bare with me))
that would make your length 7 and width 1
you have 2 lengths and 2 widths.
7+7= 14
1+1=2
=16
that would be your perimeter.
Oliver is indeed correct.
Hope this helped!!

Hit and Trial approach:' There are 4 Zepts(that has 7 legs) : 4 * 7 = 28 legs and eight Zios(that has 3 legs): 8 * 3 = 24 legs entire: = (28+24) = fifty two legs answer: 4 Zepts and eight Zios

he might be correct because if the perimiter is 16 and the area is 7 then:
7+7+1+1=16
7x1=7

He is correct if the dimensions are 7x1
P=7+1+7+1=16
A=7x1=7units squared
See videos that explain these topics on my Math help website:

yes. the dimensions are 7x1...7+7+1+1=16...area is basexheight so therefor the area could be 7.

i dont think he is right bcus how could you make a rectangle out of 7 square units
p.s if i am wrong blame my add,adhd, and dyslexia:)
ohh and i got all A's
p.s.s.s not bragging
