The answer would actually be a 110 units because the bottom left corner had 20 units and the bigger square had 90.
It is C) 2.55 because i was taught that you can subtract the negative from the positive. 5.35-2.8=2.55 and it is positive
Answer:



Step-by-step explanation:
we current vertices of the given triangle
remember that,

so we obtain:



216/1000
Simplify it by 2
Give me a thanks if it helps!!!
A = (h * b) / 2
A = 200
h = 4b
200 = (b(4b) / 2
200 * 2 = b * 4b
400 = 4b^2
400 / 4 = b^2
100 = b^2
sqrt 100 = b
10 = b ..... base is 10 cm
h = 4b
h = 4(10)
h = 40 <=== height is 40 cm
