A rectangle with perimeter 44cm is 2cm longer than it is wide what are the dimensions

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 84cm2.

Step-by-step explanation:

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
