One side of the square, RA, is 2a cm. So the area of the square is (2a)2 = 4a2 cm2

2a = 35 a = 35/2 a = 17.5
The Area of a square can be written as it's side length^2, orA = s^2if the side length is doubled, then s' is 2s.A' = (s')^2A' = (2s)^2A' = 4s^2 = 4*AWhen the side length is doubled, the area increases by a factor of 4
What is 18 divded 5
2a + 3a = 5a
A = h/2*(a + b) So 2A/h = a + b and therefore, a = 2A/h - b
