The schoolyard has an area of 3864 ft.² The section that is in the shape of a triangle is used for picnic tables what is the area of the section for picnic tables

Step-by-step explanation:

Squares have equal lengths on all sides, so we already know that 46 ft applies to the entire square.

46 x 46 = 2116

We then subtract this from 3846, so

3846 square feet - 2116 square feet = 1730

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.
