The perimeter of a rectangle is 60. The length is 10 more than the width. find the length and width

Width is 10  Length is 20

Step-by-step explanation:

Perimeter = 60

Length = W + 10

P = 2L + 2W                      Write the equation for perimeter

60 = 2(W + 10) + 2W         Substitute your variables

60 = 4W + 20

- 20          - 20                Subtract 20 from both sides

40 = 4W                        Divide both sides by 4

10 = W

width is 10 and length is 20

Step-by-step explanation:

lets give length and with a variable

length = l

width = w

hence perimeter formula is 2l +2 w

The perimeter of a rectangle is 60. The length is 10 more than the width.

l = w + 10

and

2l + 2w = 60

we can make use of the substitution method. where l is in the second formula place w+ 10 there.

2(w + 10 )+2w = 60

2w + 20  +2w = 60

4w + 20 = 60

4w = 60-20

4w = 40

w = 10

place the value of w into the first formula so we can find l

l = 10 +10

l = 20

hence this shows that the width is 10 and length is 20

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

well the answer to that is xoxoxo
