Someone please help me on this I'm unsure if my answer is correct

mafiozo [28]

Answer:

A. length = 23 cm; width = 5 cm

Step-by-step explanation:

So if 4 times the width would be $4w$ and 3 more than would be $+ 3$ , the equation would be $l = 4w + 3$ . If the perimeter is 56, then the new equation, $2(4w + 3) + 2(w) = 56$ can be formed. This simplifies to $8w + 6 + 2w = 56$ , then to $10w + 6 = 56$ , then to $10w = 50$ , and finally, $w = 5$ . So the width is 5, and now plug it into the first equation.
