Let the sides be abc and their opposite angles be ABC
Angle C: (10^2 +11^2 -15^2)/(2*10*11) = 91.04179885 degrees
Area: 0.5*10*11*sin(91.04179885) = 54.99090834
Area to the nearest integer = 55 square cm
The radius is 7 rounded to the nearest integer The circumference works out as 44 rounded to the nearest integer.
If you know the dimensions of the missing triangle, then compute the area from those dimensions, then subtract that answer from the area of the full rectangle.
It is: 0.5*4*4*sin(60 degrees) = 7 square cm rounded to nearest integer
A right angle triangle fits the dimensions given
There is no such triangle with the given dimensions because to construct a triangle the sum of its two smaller sides must be greater than its longest side. But the area of any triangle is: 0.5*base*perpenducular height
Yes depending on their dimensions
The radius is 7 rounded to the nearest integer The circumference works out as 44 rounded to the nearest integer.
A triangle by definition only has 2 dimensions.
These dimensions do not form a triangle.
Yes depending on their dimensions
If you know the dimensions of the missing triangle, then compute the area from those dimensions, then subtract that answer from the area of the full rectangle.
It can have the same area, a greater area or a less area all depending on the dimensions of their 3 sides.
Area is quadrupled (*4) and perimeter is doubled.
If both dimensions are doubled then the area is quadrupled. This is true of any geometric shape.
The area of qa triangle is always half of the area of a rectangle with the same dimensions
Area = pi*r2 = 3217 sq inches to the nearest integer.
Sorry the options are actually 64 cm2, 16 cm2, 32 cm2, 50 cm2. Thanks
