3. Q3) What is the smallest number of identical squares
that will fit in this rectangle?
Answers
Answer:
Minimum 3 squares.
Step-by-step explanation:
Let the number of identical squares that will fit in the rectangle = x
Sum of the area of the squares = Area of the given rectangle
x(Side length of the square)²= (length of the rectangle × width of the rectangle)
x(S)²= (40 × 90)
x(S)²= 3600 cm²
For the minimum numbers of the squares,
If x = 1,
S = √3600 = 60 cm
But the length of the rectangle is 40 cm, so can't be fitted in the rectangle.
If x = 2,
2S² = 3600
S² = 1800
S = √1800
S = 42.43 cm
Since, length of the rectangle is 40 cm, so the given square can't be fitted in the rectangle.
If x = 3,
3S² = 3600
S² = 1200
S = √1200
= 34.64 cm
Therefore, minimum 3 squares can be fitted in the given rectangle.

The value of x = 65.4°
Step-by-step explanation:
Given
hypotenuse = 12
To determine
The value of ∠x = ?
Using the trigonometric ratio
cos x = adjacent / hypotenuse
here:
Adjacent of angle ∠x = 5hypotenuse = 12substituting adjacent = 5, hypotenuse = 12 in the formula
cos x = adjacent / hypotenuse
cos x = 5 / 12
x = arccos (5/12)
x = 65.4°
Therefore, the value of x = 65.4°

The length of a rectangle is 3 cm greater than its
width. Its area is 108 cm. Find the dimensions
of the rectangle.
Answers
so first say the width is x so the length is +3 then the width so the length is (x+3)
the formula would be; x•(x+3) = 108
x=9
so the width is; 9 cm
and the length is; 9+3= 12cm
The length is 12 cm and width is 9 cm.
what is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Area = 108 cm²
and, The length of a rectangle is 3 cm greater than its width.
let the width of rectangle be x.
so, length = x+ 3
So, Area of Rectangle = l x w
108 = x(x+ 3)
x² + 3x -108 = 0
x² + 12x - 9x -108 = 0
x( x+ 12) -9 ( x+ 12)= 0
(x + 12)(x- 9)=0
x= -12, +9
So, length is 12 cm and width is 9 cm.
