Question

scott and tara were asked to find the area of this trapezoid. scott wrote A=1/2(24+16)(8) tara wrote A=1/2(16+24)(8) Which student is correct?Explain i can give you 5 points.

Answer 1

The SUMA mathematical operation has several properties, among them the Commutative that establishes "The order of the addends does not alter its result"

Let's develop the calculations for both students:

A (Scott) = 1/2 (24 + 16) (8) = 1/2 (40) (8) = 160

A (Tare) = 1/2 (16 + 24) (8) = 1/2 (40) (8) = 160

On the basis of this Commutative Property of the sum, which the students applied; Both Scott and Tara have responded correctly.
