A library wants to add a rectangular window made of small
glass squares. The window space is 9 feet long and 6 feet
wide. Each small glass square has sides that are 1 foot long.
Part A
How many small glass squares are needed to make the
window?
A. 54
B. 65
OD. 56

A) 54

Step-by-step explanation:

Well, first thing's first: find the area.

The formula for area is L*W

L=9 ft

W=6 ft

9*6=54 sq ft

Since the area is 54 sq ft, and each small glass square is 1 sq ft, you would need A) 54 squares of glass

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

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
