Answer:
All that I know is that the square is 40m
Step-by-step explanation:
Take 5 times 8 which is 40 and divide it by 2.
The rectangle would be 5 times the length of the diagonal line. You would then divide that by two since it is a triangle. In shorter words it would be
(5×D)÷2. D means the length of the diagonal line.
