Question 318499
The area of a rectangle is 100 square cm. If a square is built using a diagonal of this rectangle as one of its sides, the square has area 700 square cm. What is the perimeter of the rectangle?
---------------------------------------
A side of the 2nd square is sqrt(700)
--------------
Let a side of the 1st square be "x"
Equation:
x^2 + x^2 = (sqrt(700))^2
---
2x^2 = 700
x^2 = 350
x = sqrt(350)
-----------------
Perimeter of the 1st square = 4*sqrt(350)
