The perimeter of a rectangle is found by multiplying the length by 2 and the width by 2 and adding them together.
P = 2L + 2W
Filling in the information given we can find the width:
16.8 = 2(3.6) + 2W
16.8 = 7.2 + 2W
2w = 16.8 - 7.2
2w = 9.6
w = 9.6 / 2
w = 4.8 in.
It would take her 40 minutes
Answer: A. 11 . 38 + 4 . 03
B. 10 + 5 . 41
D. 9 . 2 + 6 . 21
Step-by-step explanation:
Step 1
Compute the sum of the given options
a) 11 . 38 + 4 . 03 = 15.41
b) 10 + 5 . 41= 15.41
c) 12 . 38 + 2 . 93= 15.31
d) 9 . 2 + 6 . 21 =15.41
e) 7 . 54 + 6 . 87=14.41
Step 2
Eliminate the expressions that do not give a sum of 15.41 , we have
a) 11 . 38 + 4 . 03 = 15.41
b) 10 + 5 . 41= 15.41
d) 9 . 2 + 6 . 21 =15.41
Therefore, the expressions with sum of 15.41 are A, B and D
