Josie made a quilt for her cousin's doll. The quilt had an 8 × 8 array of different color square patches. If each patch is 2 2 3 in long, what is the area of the whole quilt?

170.67 sq. inches.

Step-by-step explanation:

For her cousin's doll Josie made a quilt. There are 8 × 8 array of different color square patches in the quilt.

Then the number of square patches on the quilt will be (8 × 8) = 64.

If the side length of each square patches is inches i.e. inches, then the total area of the whole quilt will be = sq. inches. (Answer)

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
