Answer:
8.64. Her work is correct
Step-by-step explanation:
Given the expression to divide 2.16 by 0.25
Dividing both expressions to a whole number by dividing them by 0.01 is true as shown;
2.16/0.25 = (2.16/0.01)÷(0.25/0.01)
(2.16/0.01)÷(0.25/0.01) = 216/25
216/25 = 8.64
Hence her value is 8.64 making her work correct

A = 24t² + 2t
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of outer square - area of rectangle
= (5t)² - t(t - 2)
= 25t² - t² + 2t
= 24t² + 2t
