Area of square = a^2 = 4^2 = 4 x 4 = 16
answer
16
Katherine earned $15 an hour, divide $105 by the seven hours she worked
we are given two points as
(3, 16) and (5, 10)
firstly , we will find slope
slope is m
so, we can use formula

now, we can plug points



we can plug it in y=mx+b
we get

now, we can select any one points
and find b
(3,16)
x=3 and y=16

we can find b

now, we can plug back b
and we get

so, equation is

and
...............Answer
The answer is A. 88.8 cm2
Work:
74 x 2 = 148
