Answer:
base = 2
Step-by-step explanation:
area = 1/2 base * height
7 = 1/2b * 7
7 = 7b/2
cross multiply
14 = 7b
divide both sides by 7
b = 2
Answer:
2
Step-by-step explanation:
So the formula for area of a right triangle is A=B*L*1/2
Variables to remember:
H=height
B=base
A=area
We know that 7=7*B* 1/2. Since they say area is 7, height is 7.
So, we know that L has to equal 1 to make 7*B=7
However, we must remember that this is *1/2. So to make area=7, we must get 14. To get 14, we must have 7*2*1/2, which would equal 14*1/2, equaling 7.
So the answer for B is:
2
