Can someone make an equation for this pleasee

a)this is an arithmetic series

equation: 10+(n-1)d=360

note: 6hrs=60x6=360minuites

(b) 10+(n-1)d=360

n= no of days

d=common difference=2minutes

10+(n-1)2=360

(n-1)2=360-10

n-1=350/2

n-1=175

n=175+1

n=176

hi,

the area of abcd is 245.

3*24=230

4*94=1039

2*12=24

add all of them up, you get 2450

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
