Answer:
119 square centimeters.
Step-by-step explanation:
Write the problem as an equation.
2(2x+3)+2x=48
Where x is width of the rectangle. 2x+3 represents the length.
4x+6+2x=48
6x+6=48
6x=42
x=7
The width is 7 cm. Then, find the length.
(2x+3) Given
(2)(7)+3 Plug in 7 for x
14+3
17
Then, find the area, width*length
17*7=119
