Please help! I have been stuck on this. :(

45.5m^2

Step-by-step explanation:

Well you have not specified what you are trying to find but i'm guessing you want the area.

First, find the area of the rectangle by multiplying 7 x 5 because A=lw. So the area of the rectangle is 35m.

Then you find the area of the triangle which is 7x3 divided by 2(since it's a triangle you divide by 2). 7x3=21.  21 divided by 2= 10.5.

Then add both the areas together. 35+10.5= 45.5

ok then what happened.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
