Answer:
Step-by-step explanation:
Formula for area of a triangle:
Height x Base /2
Base (b) = h +4
Height = h
h + 4 x h /2 = 30cm
=> h +4 x h = 60
=> h+4h =60
=> 5h = 60
=> h = 12
Height = 12
Base = 12 +4 = 16
66 2/3
=(66*3+2)/3
=200/3
((200/3)*39)/100
=(7800/117)/100
=78/1.17
=66.7%
not so sure it is right though, but that's what I came up with. hope it helps
