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. I suggest you set:
"x" for one side
"x + 45.5" for the other side
Another Answer:-
1 Let the sides be x+45.5 and x
2 0.5*(x+45.5)*x = 2535 which transposes to: x2+45.5x-5070 = 0
3 Solving the above quadratic equation gives x a positive value of 52
4 So sides are 52+45.5 = 97.5 cm and 52 cm
5 Using Pythagoras: 97.52+522 = 12,210.252 and its square root is 110.5
6 Hypotenuse = 110.5 cm
7 Perimeter = 97.5+52+110.5 = 260 cm

What is the perimeter of an isosceles trapezoid whose parallel sides are 29.75 cm and 19.25 cm with an area of 171.5 square cm showing work and final answer to one decimal place?
Area: 0.5*(29.75+19.25)*height = 171.5 square cm Height: (171.5*2)/(29.75+19.25) = 7 cm The isosceles trapezoid will have right angle triangles at each side with a base of (29.75-19.25)/2 = 5.25 cm so use Pythagoras to find its hypotenuse:- Pythagoras: 7 squared+5.25 squared = 76.5625 and square root is 8.75 Perimeter: 8.75+8.75+29.75+19.25 = 66.5 cm
How do you create three different drawings showing a number of circles and triangles in which the ratio of circles to triangles is 2 to 3?
To create three different drawings showing a number of circles and triangles in which the ratio is 2:3 you can: Start with an equilateral triangle, draw a circle inside it, draw an equilateral triangle inside the circle, draw a circle in the triangle and then draw an equilateral tiangle in the smallest circle. Or, you could draw 3 triangles and 2 circles in a line. Or, you could draw 3 triangles on a line with 2 circles between them.
What is an asa triangle?
ASA is not a triangle, it is a method of proving that two triangles are congruent. ASA refers to showing that if two angles and a side (Angle-Side-Angle) of one triangle are the same measures as the corresponding angles and side of another triangle, then the two triangles are congruent. Since the three angles sum to 180 degrees, if two of them in one triangle are equal to the corresponding angles in the second triangle, then the third set of angles must also be equal. Consequently, ASA is equivalent to AAS and SAA. That is NOT The case with two sides and an angle, where it must be the included angle that is equal.
What is the perimeter and base angles of an isosceles triangle whose base is 9.96 cm with an area of 33.0672 square cm showing work and answers?

What is the length of the hypotenuse of a right angle triangle when its area is 54 square cm and its perimeter is 36 cm showing how you achieved your answer?
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..

What is the perimeter of an isosceles triangle whose base is 15.96 cm with an area of 84.9072 square cm showing all work and answer?
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.
