Tough to do this without a picture but here goes... Assuming the 4 semi-circles come right out of the corners of the square, they would be equal to two circles with diameters of 15cm apiece and radii of 7.5
The area of the square is 15 x 15 = 225 sq. cm
The area of the circles is 2 (pi x 56.25)
225 + 353.43 = 578.43 sq. cm

If an isosceles triangle is a triangle with 2 congruent equal sides if the third side is three times the length of the congruent sides and the perimeter is 75cm find the length of all three sides?
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
When Key on drew a square with an area of 225 square centimeters what is the perimerter of the square how did you get your answers?
The perimetre is 60cm.Because a perfect square has equal sides, which are in length the square root of the area because multiplying the length of a square by itself gives it's area. So:sqrt(225) = 15cmA square has 4 sides of the same length, so if 1 side is 15cm all 4 sides that form the perimetre must be 15*4=60cm.
