Valentin [98]3 years ago

Answer:

<em>The</em><em> </em><em>answer is</em><em> </em><em>29</em><em> </em><em>unit</em><em>.</em>

Step-by-step explanation:

Here,

given that,

DC (l) =4z+1

CD (b)=5z+2

perimeter (p)= 132

now,

perimeter of rectangle (p) is= 2(l+b)

or, 132 = 2×{(4z+1)+(5z+2)}

or, 132= 2×(9z+3)

or, 132= 18z+6

or, 18z=132-6

or, z=126/18

or, z= 7.

therefore, 4z+1=4×7+1=29

5z+2= 5×7+2=37.

As our question is about to find AB,

DC = AB. (as opposite side of rectangle is equal).

so, the valueof AB is 29unit.

area=4²+14×4+c=16+56+c=72+c

8²=64

9²=81

72+c=81

c=81-72=9

area=81  units²

A fish tank in the shape of a cuboid has length 60cm, depth 30 cm and height 30 cm.
Elena-2011 [213]

Answer:

54 liters

Step-by-step explanation:

the right term to describe the capacity is volume

volume = height × length × width

(depth and height have the same meaning)

volume = 30 × 30 × 60

volume = 54000 cm³

1 liter = 1 dm³

54000 cm³ = 54000÷ 1000

(why divided by 1000 not 10? because its cm³ which means cm × cm × cm => 10 × 10 × 10)

54000 cm³ = 54 dm³

then

54 dm³ = 54 liters
