Answer:
546 CM²
Step-by-step explanation:
Area of a Right Triangle = 1/2bl
Where b is the Base and l is the Leg (Height)
Given
Base, b = 13 MM
Hypotenuse , h= 85MM
Apply Pythagorean Theorem with an actual right triangle.
a² + b² = c²
Where a is the base , b is the leg and c is the hypotenuse
ie 13² + b² = 85²
= 169 + b² = 7225
b² = 7225 - 169 = 7056
There fore b = Square Root of 7056
= 84 CM
Therefore
Height = 84 CM
Base = 13 CM
Hypotenuse = 85 CM
Therefore Area = 1/2 Base x Height
= 1/2(13 x 84) Cm
= 546 CM²
