The perimeter of a rectangle is 20 units. if the width is 3/4 of the way what is the width of the rectangle

W = 4.3 units

Step-by-step explanation:

This rectangle has a perimeter of 20 units. Its width is 3/4 of the way assuming it means 3/4 of the length then w = 3/4 l and the length is l. We can add these expressions together and set it equal to the perimeter then solve for l.

P = l + l + w + w

20 = l + l + 3/4l + 3/4l

20 = 3 2/4 l

20 = 3 1/2 l or 20 = 3.5l

l = 5.7

This means the width will be w = 3/4 l = 3/4(5.7) = 0.75(5.7) = 4.3

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

the diameter is 16 cm. are you a teacher?
