multiply both of the first terms 2c x 5c
then do the outsides of the terms 2c x -7
then the insides -1 x 5c
then the lasts -1 x -7
now add them all together
10
- 14c - 5c + 7 = 10
- 19c + 7
Answer:
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
She placed 56 feet of fencing around her garden. This means that the perimeter of the garden is 56 feet. If the length of the rectangular garden is 20 feet, i means that
2(20 + W) = 56
Dividing through by 2, it becomes
20 + W = 28
W = 28 - 20
W = 8 feet
The formula for determining the area of a rectangle is expressed as
Area = length × width
Therefore,
Area = 8 × 20 = 160 square feet
Answer:
by measuring in feet
