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

A. length = 23 cm; width = 5 cm

Step-by-step explanation:

So if 4 times the width would be and 3 more than would be , the equation would be . If the perimeter is 56, then the new equation, can be formed. This simplifies to , then to , then to , and finally, . So the width is 5, and now plug it into the first equation.

, becomes , becomes .

So the dimensions are: length = 23 cm, width = 5 cm.

*And just to be sure, which is correct.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
