If the dimensional of his land is 29 m by 19 m how long is the fence that he need to construct?

96 m

Step-by-step explanation:

Perimeter = 2(l+b)

                 = 2 x (29 + 19)

                 = 2 x 48

                  = 96

Therefore the fence will be 96 m.

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.
