Two rectangles are similar the ratio of the lengths of their corresponding sides is 1:2 find the ratio of the peremeters of the two rectangles the find the ratio of the areas explain your answers

a. P1/P2 =(2L+2W)/(4L+4W)=
2(L+W)/4(L+W) = 2/4 = 1/2.
b. A1/A2 = L*W/(2L*2W)=(L*W)/4(L*W=1/4.
(L+W=2/4
= 1/2.
