A = LW
A = 320
L = 5W
320 = W(5W)
320 = 5W^2
320/5 = W^2
64 = W^2
sqrt 64 = W
8 = W
L = 5W
L = 5(8)
L = 40
so the length (L) = 40 cm and the width (W) = 8 cm
P = 2(L + W)
P = 2(40 + 8)
P = 2(48)
P = 96 <=====

Answer:
X= 38°
Y = 142°
Step-by-step explanation:
let the angle vertically opposite to 142° = w
therefore, w= 142° ( vertically opposite angles are equal)
hence,x+ w =180° ( two interior angles sum up to 180°)
x+ 142° = 180°
x= 180 - 142 = 48°
X = 38°
then calculating for Y
X + Y = 180° ( angles on a straight line sum up to 180°)
38+Y = 180
Y = 180- 38
Y = 142°
