Step-by-step explanation:
the area of a triangle is baseline×height/2.
the baseline is here 5.8 cm
and the height is given : 2.4 cm
so, the area is
5.8 × 2.4 / 2 = 5.8 × 1.2 = 6.96 cm²
Please elaborate more on your question so I can help you
A.
The rate is 12:2
B.
Set up a proportion:
12/2 = x/5
Multiply 5 to both sides:
60/2 = x
Divide:
30 = x
So he will walk 30 miles in 5 hours.
C.
To find out, we can divide 12 / 2.
12 / 2 = 6 miles per hour
