Answer:

Length= 20 cm

Breadth = 10 cm

Step-by-step explanation:

Given,

Perimeter = 60 cm

Let the breadth be x

We know,

2(l+b)= perimeter of a rectangle

So,

According to the question

2(2x + x) = 60

=  > 4x + 2x = 60

= >  6x = 60

=  >  x = \frac{60}{6}

=  > x = 10

Now,

Therefore,

Breadth = x

= 10 cm

and length = 2x

= 2×10

= 20 cm

  • Length=20cm
  • Breadth= 10 cm

Hope it helps you!!

Answer:

  • Length is <u>20 cm</u>
  • Breadth is <u>10 cm</u>

Step-by-step explanation:

<h3>According to the Question</h3>

It is given that,

  • Length of rectangle is twice as its breadth
  • Perimeter of Rectangle = 60cm

We have to calculate the length and

breadth of the rectangle.

Let the breadth be x cm.

then,

Length be 2x cm.

Calculating the length and breadth-

  • Perimeter of Rectangle = 2(Length+breadth)

By putting the value we get-

→60 = 2(2x+x)

→60 = 2(3x)

→60 = 6x

→x = 60/6

→ x = 10 cm

Since, breadth is <u>10</u> cm.

Therefore, Length = 2x = 2×10 = 20 cm.

  • Hence, the length and breadth of rectangle is 20 cm & 10 cm respectively.

What is the value of f(7)
kkurt [141]
F(7) means f(x) when x = 7. The x is replaced with 7.

So we'll replace every x with 7 to go from x = 7 to 3-x = 3-7 = -4

Put another way
f(x) = 3-x
f(7) = 3-7
f(7) = -4
