An artist made a stained glass window that is 3 1/2 feet by 2 3/4 feet. the artist design used squares of colored glass that measure 1/4 foot by 1/4 foot. how many colored squares did the artist use?

154

In one side of the glass window measuring 3 ½ feet, we can make  (3.5/.25) exactly 14 pieces of a ¼ foot.

The other side of the glass window which measures 2 ¾ feet we can produce (2.75/,25) or 11 pcs of a ¼ foot.

The artist used (14*11) or 154 colored squares.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

12cm

the answer is d
