Answer 2

The length of the rectangle is 7 unit.

What is rectangle?

A rectangle is a plane shape that has pair of opposite sides equal.

To calculate the length of the rectangle, we use the formula below

Formula:

• A = LW............ Equation 1

Where:

• A = Area of the rectangle
• L = Length of the rectangle
• W = Width of the rectangle

From the question,

Assuming the width of the rectangle is y unit

• A = 56 unit
• L = (y+1) unit
• W = y unit

Substitute these values into equation  1

• 56 = y(y+1)
• 56 = y²+y

Solving the quadratic equation,

• y = +7 or y = -8

Since length can not be negative,

• y = 7 unit.

Hence The length of the rectangle is 7 unit.
