Does anybody have an idea how to do this?

80 is the answer.

Step-by-step explanation:

Area of paralellogram = 1/2 × b × h

or, A = 1/2 × 16cm × 10cm

or, A = 8cm × 10cm

so, A = 80cm²

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

wait nvm i know the correct answer now its 100%   81 square feet
