The length of a rectangle is twice its width. if the area of the rectangle is 162 m2 , find its perimeter.
1 answer:
L = 2W
A = L * W
A = 162
162 = 2W(W)
162 = 2W^2
162/2 = W^2
81 = W^2
sqrt 81 = W
9 = W
L = 2W
L = 2(9)
L = 18
P = 2(L + W)
P = 2(18 + 9)
P = 2(27)
P = 54 <===== perimeter is 54 m

Answer:
DBC = 50 degrees
Step-by-step explanation:
180 - 80 = 100
2x = 100
