The perimeter or a rectangle is 54 centimeters and base length is twice the height what’s the area

162 cm^2

Step-by-step explanation:

P=2L+2H

L=2H

54=2*2H+2H

54=4H+2H

54=6H

H=54/6

H=9 ANS. FOR THE HEIGHT.

L=2*9=18 ANS. FOR THE LENGTH.

PROOF:

54=2*18=2*9

54=36+18

54=54

AREA=LW

18*9=162 CM^2 IS THE AREA.

Hope this helps, have a good day. c;

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
