150 minutes, multiply the 30 minutes (1/2hr) by the 1/5 of fence (x5)
Answer:
area = 240 in²
Step-by-step explanation:
each triangle area = 1/2(4)(15) =30 in²
30 x 8 = 240 in²
Answer:

factorise out a and x :

but from general factorization:

a » x
b » 2
therefore:

Answer:
The hight length : h
The base length : a
Apply the Pythagorean theorem in the right triangle :
h² = 13² - (10/2) = 144
h = √144 = 12 cm
S = (a x h)/ 2 = ( 10 x 12 )/2 = 60 cm²
Step-by-step explanation:
The measure would be 20 since five times four is 20
