First you would have to divide the rectangle into half, to form two congruent triangles. Then if you multiply the area of 1 of the triangles, it will give you the area of both triangles, and so the area of the triangle as a whole.

Answer: You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole.

The perimeter of a semi circle is 5.14 km. What is the semi circles diameter.
White raven [17]

Diameter of semicircle is equal to 2 km.

<h3>Explanation:</h3>

Given: Perimeter of semicircle = P = 5.14 km

d=?

Perimeter of semicircle is given by

P = (\pi \times r ) + d\\5.14 = (\pi \times r ) + d\\\\Since \ d=2r; \ r=\frac{d}{2} \\5.14 = (\pi \times \frac{d}{2}) + d\\

Simplifying the above equation

5.14 = ( \frac{(\pi \times d) + 2d}{2}) \\\\5.14 \times 2 = d(\pi +2)\\\\d=\frac{5.14 \times 2}{\pi +2 }\\

As value of pi = 3.14, equation becomes

d=\frac{5.14 \times 2}{\ 3.14 +2} = \frac{10.28}{5.14} =2 \ km

Diameter of semicircle is equal to 2 km.
