#### Answer

$160 feet (ft) of gutters

#### Work Step by Step

To find the distance around the entire roof, we will add the four sides (48, 32, 48, 32)
$48 + 32 + 48 + 32$
Start at the right of each number and add the ones digits
$8 + 2 + 8 + 2= 20$ ones
Regroup the $20$ ones as $2$ tens and $0$ ones
Write the $0$ ones in the ones column.
Write the $2$ ten in the tens column
Add the tens column next including the regrouped $2$
$2 + 4 + 3 + 4 + 3 = 16$ tens
Regroup the $16$ tens as $1$ hundred and $6$ tens
Write the $6$ tens in the tens column.
Write the $1$ hundred in the hundreds column
Add the hundreds column next which is the regrouped $1$.
Write the $1$ in the hundreds column
$160$
The sum of the three numbers is $160$
The distance is $160$ feet (ft).
