Answer:
140 ft
Step-by-step explanation:
Given data
Area= 14 square feet
Height a = 1/5 ft
Base b=????
We know that the area of a triangle is given as
Area= (1/2)B*H
substitute
14= 1/2* B* 1/5
14= B/10
cross multiply
B= 140
Hence the base is 140 ft
Answer:
Step-by-step explanation:
<u>Solving in steps</u>
- 3| 4.5 - 2| - 5 |-1.5 -(- 3)| =
- 3 |2.5| -5 |-1.5 + 3| =
- 3*2.5 - 5|1.5| =
- 7.5 - 5*1.5 =
- 7.5 - 7.5=
- 0
