Answer:
64 
Step-by-step explanation:
l x w = area
8 x 8 = 64
Answer:
<em>angle KNM = 131 degree</em>
Step-by-step explanation:
angle MNJ = angle KNL ( vertically opposite angles)
angle KNM + angle KNL = 180 degree ( linear pair)
8x-5 + 4x-19 = 180 degree
8x + 4x -5 -19 = 180
12x - 24 = 180
12x = 180+24
12x= 204
x= 204/12
x= 17
angle KNM = 8x-5
= 8(17) -5
= 136 -5
= 131
Angle KNM = 131 degree

Assuming that you typed it wrong, meaning you meant 1cm=1.5 sq meters,
then the answer is 45 meters
just multiply the length and the width to get the area
so, 5cm= 7.5 m
4cm= 6 m
7.5m multiplied by 6m is 45sq m
