Who discover herons formulas?
In geometry, Heron's (or Hero's) formula, named after Heron of Alexandria, states that the area A of a triangle whose sides have lengths a, b, and c is square root of semi perimeter multiply by semi perimeter minus a multiply by semi perimeter minus b multiply by semi perimeter minus c.
How do you find sides of perimeter of triangle when area is given?
To find the sides of a triangle when only the area is given, you can use Heron's formula, which relates the area to the semi-perimeter and the lengths of the sides. First, denote the sides as (a), (b), and (c), and calculate the semi-perimeter (s = \frac{a+b+c}{2}). The area (A) can be expressed as (A = \sqrt{s(s-a)(s-b)(s-c)}). However, without additional information, such as the ratio of the sides or one side length, you cannot uniquely determine the side lengths from the area alone.
What is formula of perimeter of semi circle?
The perimeter of a circle has the formula 2πr. Therefore the length of a semi circle is πr. But the perimeter of a semi circle also includes the diameter which is 2r. Therefore the perimeter of a semi circle = πr + 2r = r(π + 2)

How do you find the area of a rectangle with a semi circle attached to it?
Calculate the area of a rectangle and of the semicircle separately, then add.
What is the semi-perimeter of a triangle with side lengths 11 61 and 60?
Semi-perimeter means half the perimeter. Calculate the perimeter, then divide that by 2 to get the semi-perimeter.
What is the Perimeter of semicircle and quadrant circles?

A track is made up of a retangle and 2 semi-circles 45' on one side and each semi-circle is 32' how much fence is needed?
To find the total length of the fence needed for the track, first calculate the length of the rectangular part. If the width of the rectangle is 32' (the diameter of the semi-circles), then the length is 45'. The perimeter of the rectangle is (2 \times (45 + 32) = 154) feet. The two semi-circles together form a full circle with a diameter of 32', giving a circumference of ( \pi \times 32 \approx 100.53) feet. Therefore, the total length of the fence needed is approximately (154 + 100.53 \approx 254.53) feet.

Is the the semi-circles of two congruent circles always congruent?
Yes.
Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
