Answer:
Step-by-step explanation:
1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66
A = width * lengh = 23 * 10 = 230
2. width = 7
P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32
Answer:
4. area= 230cm^2 perimeter= 66cm
5. width= 7m perimeter= 32m
Step-by-step explanation:
4. a = w*l
23cm*10cm=230cm^2
p= add all sides
23cm+23cm+10cm+10cm=66cm
5. w= a/l
63m^2/9m=7m
p= add all sides
7m+7m+9m+9m=32m
