The formula for the perimeter, P, of a rectangle is P = 2(1 + w), where l is the length and w is the width of the rectangle. If the
perimeter of a rectangle is 400 cm and its width is 45 cm, what
is its length?

The perimeter is 16 inches and the area is 15 square inches.

Step-by-step explanation:

Perimeter of a Rectangle is : 2(l + w)

Area of a Rectangle is l * w

l = length

w = width

Please always note that, in a given dimension for a rectangle, the bigger value is for the LENGTH while the smaller one is the WIDTH.

From the question:

l = 5

w = 4

Perimeter

= 2(l + w)

= 2 ( 5 + 3)

= 2 ( 8 )

= 16 inch

AREA

= l * w

= 5 * 3

= 15 square inches

The perimeter is 16 inches and the area is 15 square inches.

Step-by-step explanation:

Perimeter of a Rectangle is : 2(l + w)

Area of a Rectangle is l * w

l = length

w = width

Please always note that, in a given dimension for a rectangle, the bigger value is for the LENGTH while the smaller one is the WIDTH.

From the question:

l = 5

w = 4

Perimeter

= 2(l + w)

= 2 ( 5 + 3)

= 2 ( 8 )

= 16 inch

AREA

= l * w

= 5 * 3

= 15 square inches

Perimeter of the rectangle = 2(17+8)

= 2(25)

= 50ft

Hope this helps

Perimeter of the rectangle = 2(17+8)

= 2(25)

= 50ft

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

The answer is in the image 

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
