Answer:
The answer to your question is 50 inches
Step-by-step explanation:
Data
Area = 200 in²
diagonal 1 = 8 in
diagonal 2 = ?
Formula
Area = (diagonal 1 x diagonal 2) / 2
Solve for diagonal 2
diagonal 2 = 2 x Area 2 / diagonal 1
-Substitution
diagonal 2 = 2 x 200 / 8
-Simplification
diagonal 2 = 400 / 8
-Result
diagonal 2 = 50 in
