1) this is total area of two triangle
area of a triangle=1/2*b*h
A=1/2*9*4
A=18 inches^2
multiply by 2 because there are two triangle with same measure
2A=2*18=36 inches^2
3) this is a area of rectangle and a triangle and then subtract
A2=9.3x7.8= 72.54
area of triangle A1=1/2*7.8 *3.3=12.87
A2-A1=59.69 mm^2
5) now u ca do it
C because -3 is less than 2 and we’ll stay the same
Answer: A. $0.60
Step-by-step explanation:
The prices for which the carpets were sold are
1) 100 square feet for $67
2) 200 square feet for $130
3) 400 square feet for $240
4) 800 square feet for $504. We would determine the unit cost per square foot for each of them. It becomes
1) 1 square feet costs 67/100 = $0.67
2) 1 square feet costs 130/200 = $0.65
3) 1 square feet costs 240/400 = $0.6
4) 1 square feet costs 504/800 = $0.63
The unit cost per square foot of carpet for the worst deal is $0.6

Complete question is;
Andrea is given ABC and told that a² + b² = c². She draws right triangle RTS with legs measuring a and b and hypotenuse measuring 2. Which best describes what Andrea should
do in order to prove that ABC is a right triangle?
Answer:
Andrea should show that c = 2, so: ∡ABC = ∡RTS and ∡C = ∡S. Hence, ∡C is a right angled triangle, hence ΔABC is a right triangle
Step-by-step explanation:
In this question, we are told that the given sides of the triangle are a, b and c. Now, Andrea is able to draw the two sides of the right triangle with sides = a and b and the third, hypotenuse equal to 2. Since the length of the hypotenuse = 2, then we have;
2² = a² + b²
However, we are told that c² = a² + b²
Therefore, c = 2
Hence, Andrea should show that c = 2 so ΔABC = ΔRTS and ∡C = ∡S hence ∡C is a right angled triangle since it is the angle opposite to the hypotenuse c and therefore, ΔABC is a right triangle.
