Answer:
3.975 square inches
Explanation:
Step 1
We find the length of the triangle
We solve using Pythagoras Theorem
Diagonal² = Length² + Width²
Diagonal = 4 inches
Width = 3 inches
Length² = Diagonal² - Width²
Length = √Diagonal² - Width²
Length = √4² - 3²
Length = √16 - 9
Length = √(7)
Length = 2.6457513111 inches
Length = 2.65 inches
Step 2
Area of Triangle = 1/2 × Base × Height
Base = Length = 2.65 inches
Height = Width = 3 inches
=1/2 × 2.65 inches × 3 inches
= 3.975 square inches
Therefore, the area of one of the triangles that are formed is 3.975 square inches
