2x = 2√17 and 3x = 3√17
Step-by-step explanation:
- Step 1: Given length of the rectangle is 3x and breadth is 2x. Area is 102 m². Area of the rectangle = length × breadth
102 = 2x × 3x = 6x²
x² = 102/6 = 17
x = √17
Length 2x = 2√17 and Breadth = 3x = 3√17

Step-by-step explanation:
The rule for a 90 degree counterclockwise is
(x,y) -> (-y,x)
so
C(-1,2) -> C'(-2,-1)
D(3,5) -> D'(-5,3)
E(1,2) -> E'(-2,1)
