Answer:
C) 6 in. x 3
Step-by-step explanation:
<u>using the formula</u>:
area:
6 * 3
18 in²
perimeter:
2( 6 + 3)
2(9)
18 in
Hence proved that C is the right answer.
C
Area:
Perimeter:
a = 1, b = 3.
a + b = 4
a - b = -2 Adding to eliminate b:
2a = 2
a = 1
So 1 + b = 4
giving b = 3.
y = 6
Its going by 6's
$7.50
$42 × 3 = $126
$27 × 5 = $135
$126 + $135 = $261
$275 - $261 = $14
$14 - $6.50 = $7.50
