Question

7. A rectangle's length is 1.5 times its width. The perimeter of the rectangle is 75 inches. Find

the width of the rectangle.

Answer 1

Answer: 15inches

Explanation:

Let the width = Xinches

Th length. = 1.5 x X

= 1.5xinches

Therefore,
Perimeter = 2( L + width) = 75inches

Solving the equation now by substituting the values above into the formula

Perimeter = 2( 1.5x + x ) = 75

2(2.5x) = 75

5x = 75

Now divide through by the coefficient of x which is 5 to find x

X = 75/5

= 15inches

The width of the rectangle is 15inches
