Question

You have a rectangle with the perimeter of 150 cm. One side length is

represented by 2x+4. The other side is 30 cm. What is the value of the side length represented by 2x+4?
side length represented by 2x+4?*

Answer 1

x=20.5

Explanation:

Perimeter of rectangle = 2(L+B)

L- Length and B - Breadth

150 = 2( 2x+4 +30)

150÷2 = 2x + 34

75 = 2x + 34

2x = 75 -34

2x = 41

x = 20.5
