<h3><u>Given</u><u>:</u><u>-</u></h3>

  • Perimeter of parallelogram = 66 ft

  • One side,a = 3x + 1

  • Other side,b = 2x - 3

<h3><u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u><u>-</u></h3>

Find the longest side of a parallelogram.

<h3><u>Formula</u><u> </u><u>used</u><u>:</u><u>-</u></h3>

Perimeter of parallelogram = 2 ( a + b )

<h3><u>Solution:-</u><u> </u></h3>

We know that,

Perimeter of parallelogram = 2 ( a + b )

★ Substituting the values in the above formula,we get:

⇒ 66 = 2 ( 3x + 1 + 2x - 3 )

⇒ 66 = 2 ( 5x - 2 )

⇒ 66/2 = 5x - 2

⇒ 33 = 5x - 2

⇒ 5x - 2 = 33

⇒ 5x = 33 + 2

⇒ 5x = 35

⇒ x = 35/5

⇒ x = 7 ft

Now,

One side,a = 3x + 1

★ Putting the value of x

⇒ 3 × 7 + 1

⇒ 21 + 1

⇒ 22 ft

Other side,b = 2x - 3

★ Putting the value of x

⇒ 2 × 7 - 3

⇒ 14 - 3

⇒ 11 ft

Hence,the longest Side of given parallelogram is 22 ft ( 3x + 1 ) .

Tanya says .53 is greater than .7 because 53 is greater than 7 Can you explain her mistake?
sergey [27]
Take 0.53 and 0.7 by 100 to make them percents. 0.53 times 100 is 53% and 0.7 time 100 is 70%. so 0.7>0.53

A rectangular prism has a base length of 6 units, base
Maurinko [17]

Answer:

The lateral area rectangular prism is 88 unit^2.

The area of the two bases of rectangular prism together is  60 unit^2.

The total surface area rectangular prism is 148 unit^2.

Step-by-step explanation:

Height of the rectangular prism = h = 4 units

Length of the base of the rectangular prism = l = 6 units

Width of the base of rectangular prism = b = 5 units

Rectangular prism = Cuboid

Lateral surface area of cuboid = L.S.A = 2 × h × (l+b)

Lateral surface area of rectangular prism :

L.S.A=2\times 4 units(6 units+5units)=88 units^2

Area of the base = l × b

Area of the base of the rectangular prism = 6 unit\times 5 unit=30 unit^2

Area of the two bases  = 2\times 30 unit^2=60 unit^2

Total surface area of cuboid = T.S.A = 2 ×(lb+bh+hl)

Lateral surface area of rectangular prism :

T.S.A=2\times (6unit\times 5unit+5 unit\times 4unit+4 unit\times 6 unit)

=148 unit^2
