Draw a rectangle with one side equal to 84 in. and the other side equal to 65 in. We know that area = l*w, so the area of the rectangle is 5,460 sq. in. Since Mr. Horn cut the piece of plywood in half, he produces two identical pieces of plywood, with half the amount of area as the original. So, 5,460 sq. in. divided by 2 = 2,730 sq. in.
Answer:
Pythagorean’s theorem states that if a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the side lengths of the right triangle
Given that we can plug in
a= 6 , b = 8 , c = 10
We get an equation:
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
Let's imagine we enclosed the entire shape in a 15 inch wide, 21 inch tall rectangle, area 315 sq inches.
From that rectangle we have to take away the 3x6 bottom left corner, and a strip 21-6=15 inches long and 3 inches wide on the right.
A = 15×21 - 3×6 - 3×15 = 315 - 63 = 252 sq in
Answer: D. 252 inches squared, last choice
