Find the area of the triangle QRS, R(6, 10) Q(-9, 5) S(2, -10)

Step-by-step explanation:

Given

R(6, 10)

Q(-9, 5)

S(2, -10)

Required

Area of triangle RQS

The are of RQS is calculated using the following formula;

Where x and y represent the axis of the given coordinates;

Given that R(6, 10);

Given that Q(-9, 5);

Given that S(2, -10);

By Substituting these values in the given formula;

The expression |-280| means absolute value of -280 and the value is 280

Hence, the area of the triangle is 140

the answer is option a you would get more money.it would be $250.

step-by-step explanation:

for option b 200/2=100=50% 100/2=50=25% 50/5=10=5% it would be $220
