Let the sides be x and x-7

So using Pythagoras: x2+(x-7)2 = 172 => 2x2-14x-240 = 0

Solving the quadratic equation gives x a positive value of 15

Therefore sides are: 15 and 15-7 = 8

Perimeter: 17+15+8 = 40 cm

1 Let the sides be x+14 and x 2 So: 0.5*(x+14)*x = 240 which transposes to x2+14x-480 3 Solving the above quadratic equation gives x a positive value of 16 4 Therefore the sides are 30 and 16 5 Using Pythagoras: 302+162 = 1156 and its square root is 34 6 Hypotenuse = 34 cm 7 Perimeter = 34+30+16 = 80 cm

These are basically the steps: * Use the formula for the area of a triangle to calculate the height. * Use the height and half the base to calculate the lateral sides. Use the Pythagorean Theorem. (It helps to draw a sketch, to visualize the situation.) * Add the three sides to get the perimeter.

Pythagoras' Theorem states that for any right angle triangle the height squared plus the base squared is equal to the square of the hypotenuse. In other words, after finding the square of the hypotenuse, square root your answer to find its length. Hence: (8*8)+(6*6)=64+36=100. The square root of 100=10. Therefore the length of the hypotenuse is 10 inches. In Roman numerals: (VIII*VIII)+(VI*VI)=LXIIII+XXXVI=C. The square root of C=X. Therefore the length of the hypotenuse is X inches.

Square 20.8 and square (2*76.8) then find two numbers which have been squared that have a sum of 432.64 and a product of 23592.96 Let the squared numbers be x and y:- If: x+y = 432.64 Then: y = 432.64 -x If: xy = 23592.96 Then: x(432.64 -x) = 23592.96 So: 432.64x -x^2 -23592.96 = 0 Solving the above quadratic equation: x = 368.64 or x = 64 meaning y = 64 Square root of 368.64 = 19.2 and square root of 64 = 8 are sides of the triangle Therefore perimeter: 20.8+19.2+8 = 48 cm Check: 0.5*19.2*8 = 76.8 square cm Check: 19.2^2 + 8^2 = 432.64 and its square root is 20.8 which is the hypotenuse

Augustus Pythagoras: let the equal sides be 1 unit. The square of the third side, which is the hypotenuse, is equal to the sum of the squares of the other two sides, in this case 12 and 12, a total of 2. The hypotenuse is therefore equal to the square root of two.

Let its sides be 3x and 4x If: 0.5*3x*4x = 18.375 Then: 12x^2 = 36.75 => x^2 = 3.0625 => x = 1.75 So sides are: 5.25 cm and 7 cm Using Pythagoras its hypotenuse is: 8.75 cm Perimeter: 5.25+7+8.75 = 21 cm

according to the formulae : area of triangle = (1/2) x base of triangle x height 54=(1/2)xBxH B x H = 108 now we have to factorize it.. factors can be.. (12,9),(27,4)(18,6)(36,3) now its given perimeter=36 we have to check two condition for the tringle to be right angle triangle sum of two sides > third side sum of the square of the two sides of triangle(shorter sides)= square of the third side. only one factor (12,9) satisfies both the conditions.. so the third side comes out to be 36-(12+9)=15 so the sides are...12,9,15. that's your answer..

As an intermediate step, calculate the two sides adjacent to the right angle first. Once you have that, you can easily calculate the hypotenuse and the perimeter.You'll have to write an equation to calculate the sides. Use the equation for the area of a triangle.
