Answer:
84cm^2
Step-by-step explanation:
P=2l+2w
We are given,
P=40cm
l=2w+2
Plug these into the first formula and solve for the dimensions,
length and width, of the rectangle:
40=2(2w+2)+2w Simplify
40=4w+4+2w
40=6w+4
36=6w
6=w OR the width is 6cm, therefore,
the length is
l=2(6)+2
l=14cm
To calculate the area of a rectangle, A=lw,
plug the length,14cm, and the width, 6cm, into this formula
A=(14)(6)
A=84cm2 OR the area of the rectangle is 84cm^2
Answer:
Er... um... huh?
Step-by-step explanation:
First term = (2)5^(-2*1) =2/25
2nd term = (2)5^(-2*2) = 2/ 625
3rd term = 2(5)^(-2*3) = 2/ 15625
If we divide the 3rd term by the 2nd term or the 2nd term by the first we get the common ratio
Common ratio = 1/25 or 0.04 as a decimal fraction.
