How do you calculate area of object?

Answer 1

well it depends on what object, for a square it's area = length of 1 side squared.

for a triangle, it's area = 1/2BxH

for a rectangle, it's area = WxH

for a parallelogram, it's area = BxH

for a trapezoid, it's area = 1/2(top length+base length) x height

for a circle, it's area = PIExRADIUS squared
