Question

Find the length and width of a rectangle.

Perimeter = 50
Side A = 3x + 2
Side B = x - 5

Answer 1

Length of rectangle = 3(7) + 2 = 23.

Width of rectangle = (7) - 5 = 2.

Explanation:

Answer 2

Explanation:

Perimeter = 2 * (Side A + Side B)

= 2 * (3x + 2 + x - 5)

= 2 * (4x - 3)

= 8x - 6.

We have 8x - 6 = 50, so 8x = 56 and x = 7.

Length of rectangle = 3(7) + 2 = 23.

Width of rectangle = (7) - 5 = 2.
