Question

What is the formula for the area of:

Answer 1

Answer:

Triangle- (height × base)/2

Rhombus-(First diagonal×Second diagonal)/2

Trapezoid- (First base+second base)/2×height

N-gon= (Side-2)*180

Answer 2

Answer:

For Triangle: Area equals base times height divided.

For Rhombus: A = ½ × d1 × d2

For Trapezoid: A= 1/2h x b1+b2

For N-Gon: A = (n × s × a)2 A = ( n × s × a ) 2
