Answer 1

Answer:

1) w = x+2

2) L = 12

3) w = 9

4) A = 108

Step-by-step explanation:

The rectangle has a length of x+5 and a perimeter of 4x+14.

Perimeter of a rectangle is given by all the lengths plus all the widths, ie 2*width and 2*length.

Perimeter = 2w + 2L

4x+14 = 2w + 2(x+5)

4x + 14 - 2x - 10 = 2w

w = 2x + 7 - x - 5

w = x+2      Width of the rectangle in terms of x.

If perimeter of rectangle is 42, what is the length?

Perimeter = 42 = 4x+14

28 = 4x

x = 7

L = x+5

L = 7+5

L = 12

If perimeter of rectangle is 42, what is the width?

Perimeter = 42 = 4x+14

28 = 4x

x = 7

w = x+2

w = 7+2

w = 9

Area equals length times width. What is the area of the rectangle.

A = L*w

A = 12*9

A = 108
