Answer:
A = 54cm^2
Step-by-step explanation:
A = (base × height)/2
base = 9cm
height= 12cm
A = (9 × 12)/2
A = 108/2
A = 54
Answer:
7.81
Step-by-step explanation:
Using the formula for finding the distance between two points as shown:
TU = √(y2-y1)²+(x2-x1)²
Given T = (4,-2) and U = (-2,3)
x1 =4, y1 = -2, x2 = -2, y2 = 3
Substituting this values into the formula, we have;
TU = √{3-(-2)}²+(-2-4)²
TU = √(3+2)²+(-2-4)²
TU = √5²+(-6)²
TU = √25+36
TU = √61
TU = 7.81
The distance between the two points is 7.81
