The area of the shadow part in the square accounts for one sixth of the area of the circle and one fifth of the area of the square; the area of the shadow part in the triangle accounts for one fifth of the area of the circle The simplest integral ratio of the area of a square, a circle and a triangle

The area of the shadow part in the square accounts for one sixth of the area of the circle and one fifth of the area of the square; the area of the shadow part in the triangle accounts for one fifth of the area of the circle The simplest integral ratio of the area of a square, a circle and a triangle

Circle area: square area = 6:5; circle area: triangle area = 8:9. The least common multiple of 6 and 8 is 24, so it is 20:24:27

The area of the shadow part in the figure is 24 square centimeters. It is known that the shadow part accounts for 14% of the triangle area and 118% of the square area. Find the ratio of the square area to the triangle area

(24 / 118): (24 / 14), = 432:96, = 9:2; a: the ratio of square area to triangle area is 9:2

The two sides of an isosceles triangle are 4cm and 6cm, and the circumference of the isosceles triangle is calculated

When the waist length is 4 m and the bottom length is 6 cm, the circumference of a triangle is 4 + 4 + 6 = 14 cm; when the waist length is 6 m and the bottom length is 4 cm, the circumference of a triangle is 4 + 6 + 6 = 16 cm; when the isosceles triangle is 14 cm or 16 cm
