A rectangle has a length of 12 yards less than 3 times its width. If the area of the rectangle is 135 square yards, find the length of the rectangle.

The length is 15 yards

Step-by-step explanation:

Given

Represent the width with W and length with L: So

Required

Determine the length of the rectangle:

Area is calculated as thus:

Substitute 3W - 12 for L and 135 for Area

Reorder:

Divide through by 3

Expand:

or

or

But width can't be negative

So:

Recall that:

Hence, the length 15 yards

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
