I need help with this is dont really understand it

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

mtrs.

step-by-step explanation:

first sa=180 square meters

as it is given that

putting the value of sa

mtrs.

now, when sa = 120 sq mtrs. using the formula we get

mtrs.

the side of cube with surface area 180 sq mtrs. is longer by side of cube with surface area 12 sq. mtrs. by

mtrs..
