The area of a rectangular wall of a barn is 85 square feet. Its length is 12 feet longer than the width. Find the length and width of the wall of the barn.

Length = 17 feet, Width = 5 feet

Step-by-step explanation:

Given:

The area of a rectangular wall of a barn is 85 square feet.

Its length is 12 feet longer than the width.

Question asked:

Find the length and width of the wall of the barn.

Solution:

Let width of a rectangular wall of a barn =

As length is 12 feet longer than the width.

Length of a rectangular wall of a barn =

As we know:

Subtracting both sides by 85

As width can never be in negative, hence  width of a rectangular wall of a barn = = 5 feet

Length of a rectangular wall of a barn =

Therefore, length and width of the wall of the barn is 17 feet and 5 feet respectively.

step-by-step explanation:

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
