Arose garden is designed by joining a rectangle and a semicircle, as shown below. the rectangle is
20ft
long and
16ft
wide. if the gardener wants to build a fence around the garden, how many feet of fence are required? (use the value
3.14
for
π
, and do not round your answer. be sure to include the correct unit in your answer.)

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

the answer is d on edge
