Answer:
130ft
Step-by-step explanation:
5x -5.5 = -27.5
5x -5.5 = 27.5 + 10 = 37.5
27.5 x 2 = 55
27.5 + 10 = 37.5 x 2 = 75
55 + 75 = 130 ft
21x+9ft, since x has no value that I know of. Otherwise sub that number in for x and complete the equation.
Explanation: it’s a rectangle so the width and length are the same so just multiple the width and length by themselves add all like terms (x’s and numbers) you’ll get the answer.
