The diagonal of a square is usually found using Pythagoras's theorem, a2 + b2 = c2. Since this is a square, a = b; thus: c2 = 2s2, where s is the side length and c is the diagonal.
s = square root(c2/2) = square root(625/2) = square root(312.5) = 17.8in
The dimensions of a square whose diagonal is 25inches is 17.8in x 17.8in (rounded to the nearest tenth)
15 and 20 inches because these dimensions comply with Pythagoras' theorem and the area of the rectangle.
The area of a square whose perimeter is 36 inches is: 81 square inches.
36 square inches.
It is: 72A cubic inches
7 inches
720 in3
It is 486 square inches.
There are many different triangles that have an area of three square inches, here's one way to draw one: Draw a rectangle whose area is six square inches (or imagine what one's dimensions would be, e.g. 6x1 or 3x2) and cut it in half diagonally to make a right triangle that has an area of three square inches.
The area of a circle whose diameter is 12 inches is: 113.1 square inches.
The area of a circle whose diameter is 18 inches is: 254.5 square inches.
