Question

A mathematician has derived the following formula for calculating the area of a :

A = (x+y) x z
For the measured values:
x = 9.8 cm
y = 1.5 cm-
z = 12.4 cm
Calculate the area of the object in dn² using the mathematician's formula.
46.7

Answer 1

The area formula is: A= (1/3) * (x + y) * z

x = 9.80 cm y = 1.50 cm z = 12.40 cm

Area = (1/3) * (9.80 + 1.50) * 12.40

Area = (1/3) * (11.30 * 12.40)

Area = (1/3) * 140.12

Area = 46.71 square centimeters
