(3 + 7/2, -5 + 9/2)

(10/2, 4/2)

(5, 2)

2. S(-8, -6) and T(-4, 6)

Use the midpoint formula:

(x1 + x2/2, y1 + y2/2)

(-8 + -4/2, -6 + 6/2)

(-12/2, 0/2)

(-6, 0)

The length of a rectangle is three times its breadth if the breadth is decreased by 2 m and breadth increased by 4 m the area of

White raven [17]

Answer:

Let the breadth is x, then the length is 3x.

The area is:

A = lw = 3x*x = 3x²

The breadth is decreased by 2 m:

w = x - 2

The length is increased by 4m:

l = 3x + 4

The area is now:

(x - 2)(3x + 4) = 3x² - 1/3(3x²)
3x² + 4x - 6x - 8 = 2x²
x² - 2x - 8 = 0
x² - 2x + 1 = 9
(x - 1)² = 3²
x - 1 = 3
x = 4

The breadth was 4 m and the length 12 m
