Answer:
Step-by-step explanation:
Let the number of floors = x
Number of apartments per floor = 4x
4x *x = 100
4x² = 100
x² = 100/4
x² = 25
x =√25
x = 5
Number of apartments on each floor = 4*5 = 20

<h3> <u>Answer</u><u> </u><u>:</u></h3>
<h3><u>Explaination :</u></h3>
In the question it is given that the length is 4 cm more than the width so let us assume the width as x.
Therefore,
- Length (l) = 4 + x
- Breadth = x
As we know the formula of calculating the perimeter of rectangle is,
Here,
- P is perimeter
- l is length
- b is breadth
Putting their respective values,
=> 14 = 2 (x + 4 + x)
=> 14 = 2 × (x + 4 + x)
=> 14 = 2x + 8 + 2x
=> 14 = 4x + 8
=> 14 - 8 = 4x
=> 4x = 6
=> x = 6 / 4
=> x = 3 / 2
=> x = 1.5

Hello,
As √88=9,3808315196468591091312602270889....
==>9<√88<10
Answer C
X = longest side , y = middle side , z = shortest side
P = x + y + z
P = 82
x = 2z + 7
y = z + 15
82 = (2z + 7) + (z + 15) + z...combine like terms
82 = 4z + 22
82 - 22 = 4z
60 = 4z
60/4 = z
15 = z
so the shortest side (z) is 15 cm
the second side (y) is : z + 15......15 + 15 = 30 cm
and the longest side (x) is : 2z + 7.....2(15) + 7 = 37 cm
