Gabriella's window store made a mosaic for the community center. the mosaic had a 7 × 7 array of different color square tiles. if each tile is 1 3/ 4 ft long, what is the area of the whole mosaic? will give brainliest and a lot of points if you answer right now!

150 1/16 sq ft

Step-by-step explanation:

The mosaic had a 7 × 7 array of different color square tiles.

each square tile is 1 3/ 4 ft long or 1.75' long

so each square tile area = one side x one side

= 1.75 x 1.75

= 3.06 sq ft

7 x 7 array has 7 x 7 = 49 tiles

area of whole mosaic = 49 x 3.06

= 150.06 sq ft

or = 150 1/16 sq. ft

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
