Find the area of a composite shape below. Really confused on this one. can i get a step by step explanation please :) <3

390 ft^2

Step-by-step explanation:

We will break this shape into two rectangles, one that is 7 ft wide by 30 ft long

and the other that is 25ft-7ft wide by 30ft -20 ft  long  (18 ft by 10 ft)

1st:  7 ft by 30 ft

A = l*w = 7*30 = 210 ft^2

2nd:  18 ft by 10 ft

A = l*w = 18 * 10 = 180 ft^2

Add the areas together

210+180 = 390 ft^2

390 ft²

Step-by-step explanation:

25 - 7 = 18

(30×25) - (20×18)

= 390 ft²

468

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
