Triangle shaped field (triangle ABC) has side AB = 129 m. path XY is parallel to the side AB which divided triangle ABC into two parts with same area. What will be the length of the path XY? Help please geodesist ... - Parallelogram

Calculate the area and perimeter of a parallelogram whose two sides are long a=24 cm b=22 cm and height h_{a}= 6 cm long. - Equilateral triangle

Calculate the side of an equilateral triangle, if its area is 892 mm^{2}. - XY triangle

Determine area of triangle given by line 7x+8y-69=0 and coordinate axes x and y. - Heron backlaw

Calculate missing side in a triangle with sides 17 and 34 and area 275. - Slope of the pool

Calculate slope (rise:run) of the bottom of swimming pool long 30 m. Water depth at beginning of pool is 1.13 m (for children) and depth at end is 1.84 m (for swimmers). Slope express as percentage and as angle in degrees. - Wheat

The rectangle shaped field with dimensions 1268 m and 745 m harvested last year was 4959 q wheat. (1 q = 1 quintal = 100 kg). During the year, it was necessary to fix the pipe and therefore did kick wide 4 m parallel to the side of the field 745 m, where n - Shooter
