Given a ratio of 3:4 for the perpendicular sides in four right triangles:

i. The difference in sides yields 3x = 72m, 4x = 96m.

ii. With a 24m hypotenuse, sides are 72/5m and 96/5m.

iii. For a 24m perimeter, the solution seems inconsistent.

iv. Area of 24sqm yields sides of 6m and 8m.

Given: Ratio of perpendicular sides = 3:4

i. The difference in the lengths of the perpendicular sides is 24 meters.

Let the lengths of the perpendicular sides be 3x and 4x meters.

Given: 4x - 3x = 24

Solving: x = 24

Therefore, perpendicular sides are 3x = 72 meters and 4x = 96 meters.

ii. The hypotenuse is 24 meters.

Using Pythagoras theorem:
(3x)^2+
(4x)^2 = hypotenuse^2


9x^2 +
16x^2 =
24^2


25x^2 = 576


x^2 = 576 / 25

x = 24 / 5

Perpendicular sides: 3x = 72 / 5 meters, 4x = 96 / 5 meters

iii. The perimeter is 24 meters.

Given: Perimeter = 3x + 4x + hypotenuse = 24

Substituting the values: 3x + 4x + 24 = 24

Solving: 7x = 0

This leads to an inconsistency, indicating an issue with the provided information.

iv. The area is 24 square meters.

Area of a right triangle = 0.5 * base * height

Given: (3x * 4x) / 2 = 24

Solving:
12x^2 / 2 = 24


12x^2= 48


x^2 = 48 / 12

x = √4

x = 2

Perpendicular sides: 3x = 6 meters, 4x = 8 meters

For cases ii and iv, the lengths of the sides are resolved, but the information for cases i and iii seem to be incorrect or inconsistent as they lead to invalid solutions.
