Step-by-step explanation:

We can solve this question using proportion

Perimeter of the square/Time is takes to unlock

We are told in the question that:

The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds.

Hence, the perimeter of the square after 1.5 seconds is:.x = unknown

32/2.5 = x/1.5

Cross Multiply

2.5x = 32 × 1.5

x = 32 × 1.5/2.5

x = 19.2 centimeters

Aneli [31]

Answer:

54 sq ft

Step-by-step explanation:

Area of a triangle is given by :

Area = (1/2) x base x height

in our case, if we assume the base of the right triangle to be 12 feet, then the height is 9 feet

Area = (1/2) x 12 x 9

Area = 54 sq ft
