step -by- step Step-by-step explanation.
From the the question, the
Length, l= 120 feet.
Width, w= 55% of l
This implies that;
w=0.55×120=66 feet.
Area of rectangle is given by the relation ;
![A =l * w](https://img.qammunity.org/2021/formulas/mathematics/middle-school/hypdcydf0jgtv1eo8k8k51x1jkr36j1u8k.png)
By substitution,
![A =120* 66](https://img.qammunity.org/2021/formulas/mathematics/middle-school/auee0pkbw5lhaluqc6g4kuebd9y4djul7y.png)
![\implies A =7920](https://img.qammunity.org/2021/formulas/mathematics/middle-school/o5cgyt4gy32medwslf4han17ppghhrgo51.png)
Therefore the area of the rectangular stage is 7920 square feet.
