Question

If s = 1/4 unit and A = 80s^2, what is the value of A, in square units? ____ square unit(s). (Input whole number only.)

Answer 1

If s = 1/4 unit and A = 80s^2

A = 80 (1/4)^2

A = 80 (1/16)

A = 5

Answer

5 square units

Answer 2

5 square units

substitute s = $\frac{1}{4}$ into the equation

A= 80 × ($\frac{1}{4}$)² = 80 × $\frac{1}{16}$ = $\frac{80}{16}$= 5 square units
