Answer:

The area of a triangle is the region enclosed between the sides of the triangle. Area of ΔABC = 1/2 × Base × Height. Let us know the basics of the area of a triangle. If ABC is an equilateral triangle, Area of ΔABC = (√3/4)a2 where a is the length of a side of the equilateral triangle.

Find the area or this triangle ​
Arlecino [84]

Answer:

Area of triangle = 15 square units

Step-by-step explanation:

We need to find area of the triangle, given the vertices:

A=(4,0)

B=(1,5)

C=(7,5)

The formula used is: Area\:of\:triangle=\frac{1}{2}(x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2))

We have: x_1 =4, y_1 =0, x_2 =1, y_2=5, x_3=7 , y_3=5

Putting values and finding area

Area\:of\:triangle=\frac{1}{2}(x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2))\\Area\:of\:triangle=\frac{1}{2}(4(5-5)+1(5-0)+7(0-5))\\Area\:of\:triangle=\frac{1}{2}(4(0)+1(5)+7(-5))\\Area\:of\:triangle=\frac{1}{2}(0+5-35)\\Area\:of\:triangle=\frac{1}{2}(-30)\\Area\:of\:triangle=-15

We will be ignoring negative sign, because area of triangle is positive.

So, Area of triangle = 15

Gekata [30.6K]

Answer:

$46.746

Step-by-step explanation:

Allen is buying a video that originally cost = $ 49

Discount coupon = 10%

Sales tax= 6%

Hence, the price of video after discount coupon and sales tax= $ 49 ×\frac{100-10}{100}×\frac{100+6}{100}

Hence, the price of video after discount coupon and sales tax= $ 49 ×\frac{90}{100}×\frac{106}{100}

Price of video after discount coupon and sales tax= $ 49 × 0.9× 1.06

price of video after discount coupon and sales tax=  $46.746

Hence, the correct answer is $46.746
