Question

Jasper Wrote a formula for the area of triangle RST in terms of only the sides and angles. His steps are shown.

Step 1: A =
1: A = 1/2 hs
Step 2: sin(R) = h/r
h = rsin(R)
Step 3: A = 1/2(r)(s)sin(R)

Identify the error in Jasper's work, then replace one term in his equation to write a correct equation for the area.

A= 1/2rs sin(R)

Answer 1

Answer 2

The correct equation for the area of the triangle is A= 1/2st sin(R).

What is the area of triangle?

The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to the base times the height divided by half.

Area = (1/2)×Base×Height

Correct calculation for the area of the triangle.

• Step 1: Use formula to calculate area.

A = (1/2)×Base×Height

Base = s

height = h

A = 1/2 hs

• Step 2: Use sine function to get the value of height h.

Sine (R) = Base/Hypotenuses

sin(R) = h/t

h = tsin(R)

• Step 3: Substitute the value of h in area A.

A = 1/2(t)(s)sin(R)

Therefore, the correct area of the triangle is A = 1/2(t)(s)sin(R).
