I used my calculator and it says c=16n-t+2b
Answer:
choice 1
Step-by-step explanation:
A= 250 m²
Each triangle gets:
250/4= 62.5 m²
l=12 m, h= 10.4 m ⇒ A= 1/2*12*10.4 m²= 62.4 m² is the correct option, the rest give greater area
Answer:
Perimeter = 60
Step-by-step explanation:
because l bisects AB:
3y+1 = 5y-5
reduce:
2y = 6
y = 3
and:
2x+4 = 4x-12
reduce:
2x = 16
x = 8
AB = (3y+1) + (5y-5)
AB = 8y-4
substitute for y
AB = 8(3)-4
AB = 20
Perimeter = (2x+4) + (4x-12) + 20
reduce:
perimeter = 6x+12
substitute for x:
Perimeter =6(8)+12
reduce:
Perimeter = 60
Yes, it is also a square number
