Calculate the area of a rectangular field with perimeter 88 cm and length 18 cm​

Mathematics

gogolik [260]2 years ago
3 0

The area of the rectangular field is 468cm².

Step-by-step explanation:

If, length is 18cm; width is unknown( let x represent width). Then,

<u>Perimeter of a rectangle</u>= Length + Width+ Length + Width

88= 18 + x + 18 + x

88= 36 + 2x

88-36 =2x

52= 2x

52/2=2x/2

26=x

•x=26cm

<em>The</em><em> </em><em>width</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>rectangle</em><em> </em><em>is</em><em> </em><em>2</em><em>6</em><em>c</em><em>m</em><em>.</em>

<u>Area of a rectangle</u>= Length × Width

=18cm×26cm

= 468cm².

find the length of the base of a square pyramid if the volume is 1,024 cubic inches and has a height of 12 inches. (6 points) 4
Leokris [45]
To solve, we use the volume of a square pyramid formula which is expressed as the product of the area of the base (a²) and the height divided by three(h/3).

Volume = a² (h/3)
1024 in³ = (a²) (12 in/3)
a² = 1024 in³ · 3 /12
a = √256 in²
a = 16 in

Thus, the length of the base is 16 in.

Answer:

To calculate the volume of a cylinder, you need the radius or diameter of the circular base or top and the height of the cylinder. The volume of a cylinder is equal to the product of the area of the circular base and the height of the cylinder. The volume of a cylinder is measured in cubic units.

Quadrilateral QRST is a parallelogram. Solve for x (3x+5) (9x-17)
Naddika [18.5K]

Given:

Consider the below figure attached with this equation.

Quadrilateral QRST is a parallelogram.

To find:

The value of x.

Solution:

We know that the sum of two consecutive interior angles of a parallelogram is 180 degrees because they are supplementary angles.

In parallelogram QRST,

m\angle Q+m\angle T=180^\circ

(3x+5)^\circ+(9x-17)^\circ=180^\circ

(12x-12)^\circ=180^\circ

On comparing both sides, we get

12x-12=180

12x=180+12

12x=192

Divide both sides by 12.

x=\dfrac{192}{12}

x=16

Therefore, the value of x is 16.

What are the factors of a polynomial with the following zeroes: -1, ⅔, 2 ?
mylen [45]
When a zero of a polynomial is "c", a factor is (x - c).
If the zero is p/q, a factor will be (x - p/q) or (qx - p).

The appropriate choice here is
  d (x+1)(3x-2)(x-2)
