Given the base b and height h of a triangle, calculate the area A using A=(1/2)bh. Calculate A when b=12 foot and h= 2 feet

area = 12 sq.feet

Step-by-step explanation:

if b = 12 feet

h = 2 feet

then area of triangle

= 1/2 ( b × h )

= 1/2 ( 12×2 )

= 1/2 × 24

= 12 sq.feet

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

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.
