A square tile measures 20cm by 20cm. A rectangular tile is 3cm long and 2cm narrower than the square tile what is the difference in area between the two tiles

346 cm²

Step-by-step explanation:

Area of square:

Area =

A = 20*20

A = 400 cm²

Area of rectangle:

Length = 3 cm

Width = 20-2 = 18 cm

Now, The Area:

Area =

Area = 3 * 18

Area = 54 cm²

Now, The difference in their areas:

=> 400-54

=> 346 cm²

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

probably the last option
