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

Hope this helps! ;)
