The shorter leg of a 30°-60°-90° triangle is 7.4 meters long. find the perimeter.

The perimeter of the 30°-60°-90° triangle whose shorter leg is 7.4 meters long is; 35meters

The ratio of the legs of a 30°-60°-90° triangle is;

1 : √3 : 2.

where, the shorter leg is 1.

The perimeter of the triangle is therefore the sum of all three legs and is evaluated as follows;

Perimeter = 7.4 (1 + √3 + 2)Perimeter = 7.4 × 4.73Perimeter = 35.0 meters.

The ratio of the sides of a 30 60 90 triangle are 1 : sq root (3) : 2
So the sides are
7.4
7.4 * sq root (3) = 12.82
7.4 * 2 = 14.8

Perimeter = 7.4 + 12.82 + 14.8
Perimeter = 35.02

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
