A rectangle has a length of 12 m and a width of 400 cm. What is the perimeter of the rectangle? (Hint: all units must be the same) A.2000 cm
B.3200 cm
C.824 cm
D.1600 cm

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

l = 12m

w = 400 cm

First we must convert the length from meters to centimeters

1 m = 100 cm

12 m = 12 × 100 = 1200 cm

So l = 1200 cm

Substitute the values into the above formula

We have

Perimeter = 2(1200) + 2(400)

= 2400 + 800

We have the final answer as

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
