The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
Using 3.14 as Pi the area of circle is: 907.46
Using pi as 3.14 it works out that the diameter is 20 cm
That depends on the geometric figure.
A = Pi(r)2: A circle with a radius of 8 cm has an area of 201.06 square cm.
the area o rectangle is 6 x 12 = 72 and the area of trapezoid is 1/2 (12+16) X 7 = 98. The sum is 72 + 98 = 170 Square cm
42 cm
3400 sq. cm
29cm times 13cm= 377cm squared :)
It can have any shape you like.

If it was a square, the answer would be 81 square cm. The area will be the product of two numbers whose sum is half the perimeter.
A circle with a radius of 16 cm has an area of 804.25 square cm.
Using 3.14 as Pi the area of circle is: 0
Using the cosine and sine rules the area of the triangle works out as 457 square cm rounded.
