Answer:
16
Step-by-step explanation:
note that in a 45° - 45° - 90° triangle the legs are equal in length, since triangle is a right isosceles
let x be the length of the leg
using Pythagoras' identity on the triangle, then
x² + x² = 32²
2x² = 1024 ( divide both sides by 2 )
x² = 512 ( take the square root of both sides )
x = = 16
the legs have length 16
Answer: 2770.9 in^2
Step-by-step explanation:
You need to find the area of each of part of the rug. I would solve it by finding the area of the quadrant and then the area of the two semicircles and add them together.
The Quadrant
The Two Semicircles add up to one total circle so you solve for a full circle.
Then you add the two parts you solved for together
1385.44 + 1385.44 = 2770.88 or 2770.9 in^2
