Answer: the area of the triangle is 23.4 cm²
Step-by-step explanation:
The given triangle is not a right angle triangle. Since two sides and one angle are known, we can either apply the Heron's formula or the Sine formula which is expressed as
Area of triangle = 1/2abSinC
Where a and b are the sides of the triangle and C is the given angle. Therefore,
Area = 1/2 × 8.2 × 6.4 × Sin63
Area = 1/2 × 8.2 × 6.4 × 0.8910
Area = 23.4 cm² to the nearest tenth.

Answer:
3 6/10 square feet
Step-by-step explanation:
The area of the rectangle is 8 1/10
The width of the rectangle is 2 1/4
We are required to find the length
Area= length × width
Length= Area/width
= 81/10 / 9/4
= 81/10 × 4/9
= 36/10
= 3 6/10
Hence the length of the rectangle is 3 6/10 square feet
