Answer:
20 cm
Step-by-step explanation:
First, find the length of one side of the square. Here A = 25 cm^2 = s^2, where s represents that length. Thus, s = 5 cm.
Next, find the perimeter of the square. P = 2(length) + 2(width). For a square, where length=width, P = 4s.
In this problem, P = 4(5 cm) = 20 cm
Answer:
A = (x + 7)(x + 9)
Step-by-step explanation:
Let the width w = x
then length l = w + 4 = x + 4
Area = length x width
= x(x+4)
Then the the width is increased by 7 units and the length increased by 5 units.
w = x + 7
l = (x + 4) + 5 =x + 9
A = (x + 7)(x + 9)
The answer to this question would be 612
