Answer:
B
Step-by-step explanation:
Let's call the shortest side a. The longest base, b, is 8cm longer than a. The height, h, is 2cm longer than a.
b = a + 8
h = a + 2
A = (a + b)h/2
48 = (a + (a+8))(a+2)/2
= (2a+8)(a+2)/2
= (2a^2+12a+16)/2
48 = a^2+6a+8
a^2+6a-40=0
Now, we factor this:
(a + 4)(a - 10)=0
a = -4, 10
a (length) cannot be a negative no. so the only possible answer is a = 10.
b = 10 + 8 = 18
h = 10 + 2 = 12
The answer is B
Hope this helps!
