I don't understand...Please Help?

Question

Define as perimeter, area, or volume.
a.) 3m^2
b.) 5 m
c.) 8m^3

Can someone explain these, and then give me the answer?...Thank you so much!

Answer 1

a.) 3m^2 Area because of the exponent 2
b.) 5 m perimeter because of the exponent 1
c.) 8m^3 volume because of the exponent 3

Answer 2

Perimeter is a length,so just meters.
Area is Length x Bredth(Rectangle) or Pi r^2(for circle) so Meter x Meter=Meter^2
Volume is Length x Bredth x Height(For Cuboid) so MeterxMeterxMeter=Meter^3
so 3m^2--Area,5m---perimeter &8m^3--volume.ans

Answer 3

a) 3m^2
a^2 will always be the area of a two dimensional figure: it does not have to be a square.

EX: 3m(l) * m(w)

b) 5 m
a^1 will always be a perimeter of a two dimensional figure

EX: 2m+1m+1m+1m

c) 8m^3

a^3 will always be the volume of a 3- D figure

EX: 2m*2m*2m.

Answer 4

1) is an area as expressed in m^2
2) is a perimeter (units meter)
3) is a volume ( units cubic meter)

Answer 5

area is always in square units, volume is always in cubic units, and perimeters is always in linear units.
So a.) is an area since it is in square meters, b is a perimeter, and c is a volume.

Answer 6

a perimeter is a linear measure, so the unit will have an exponent of 1
An area will have squared units of measure
volume will have cubic units of measure
