Mr. crow, the head groundskeeper at high tech middle school, mows the lawn along the side of the gym. the lawn is rectangular, and the length is 5 feet more than twice the width. the perimeter of the lawn is 250 feet. homework ✎

use the 5-d process to find the dimensions of the lawn.

use the dimensions you calculated in part (a) to find the area of the lawn.

what are the answers and how do i solve it you

Dimensions, Length = 85 feet and Width = 40 feet

Area of lawn = 3400

Step-by-step explanation:

Given: Lawn is rectangular in shape

          Length of lawn is 5 feet more than twice its breath/width

           Perimeter of Lawn = 250 feet

To find: (a) Length and width of lawn

             (b) Area of Lawn

First let the a variable for width/breadth. Say, Width = b.

So, the length of lawn = 2b + 5

Perimeter of Rectangle = 2 × ( length + width )

Now, substitue given values in this formula

∴ Perimeter of Lawn = 2 × ( 2b + 5 + b )

∴width = 40 feet

⇒ length = 85 feet

Now we find are of lawn using formula of area of rectangle

Area of lawn = length × width

                     = 85 × 40

                     = 3400

Dimensions, Length = 85 feet and Width = 40 feet

Area of lawn = 3400

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
