If the area ratio of two similar triangles is 1:4, then the similarity ratio of the two triangles is 1:4

If the area ratio of two similar triangles is 1:4, then the similarity ratio of the two triangles is 1:4

1: The area ratio is the square of the similarity ratio

The ratio of the corresponding midlines of two similar triangles is 3:1. If the area of one triangle is 9, the area of the other triangle is 2

81 or 1

What's the area of the triangle if it's 5 meters long and 6 meters long?

If it is 5, half of the bottom is 3 and the height is 4
Area = 0.5x6x4 = 12 square meters
If the waist is 6, the bottom half is 2.5, height = 5.45
Area = 0.5x5.45 = 13.625 M2

In a trapezoid with an upper bottom of 12 cm, a lower bottom of 8 cm and a height of 4 cm, cut off the largest triangle, and the remaining area is () square cm

The area of trapezoid is 1 / 2 × (12 + 8) × 4 = 40 cm and 178;
The largest triangle that can be cut out has a base of 12, a height of 4, and an area of 1 / 2 × 12 × 4 = 24cm;
So the remaining area is 40-24 = 16 square centimeters

A triangle has a side length of 1.2cm and an area of 3.6 square centimeters. What is the height of this side?

The area of a triangle is equal to half of its base multiplied by its height
h=3.6 * 2 /1.2=6
