You are painting a panel with a diamond-shaped window, as shown. You have to put up tape around the edge of the window to keep the paint off. Find the length of tape you need to nearest inch

Length of tape required = 10 inches

Step-by-step explanation:

Length of the tape around the edge of the window = perimeter of the window

Since, distance between two points and is given by,

d =

For the side having extreme ends as (15, 18) and (21, 10),

    = 10 inches

Side with extreme ends (21, 10) and (15, 2),

    = 10 inches

Distance between (15, 2) and (9, 10),

   = 10 inches

Distance between (9, 10) and (15, 18),

    = 10 inches

Therefore, perimeter of the window =

                                                            = 10 + 10 + 10 + 10

                                                            = 40 inches

Length of tape required = 10 inches

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

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
