A triangle has a base of 5 cm and a height of 8 cm what is the area of the triangle?a. 10 cm B.13 cm² c.20 cm² D.40 cm²

529 and 531

step-by-step explanation:

umm im not really sure because i never had to do this

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
