A tile installer plots an irregular shape on grid paper. Each square on the grid represents 1 square
centimeter. What is the area of the irregular shape?

i believe the answer is the polygon, heptagon.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

thats not a system of equations, that is a solution
