Question

A rectangle has a length of x+5 cm and a width of x cm. The perimeter of the rectangle is 50 cm. What is the value of x?

Answer 1

x = 10

Explanation:

perimeter is the sum of all sides

2 sides = 'x+5' cm

2 sides = 'x' cm

2(x + 5) + 2x = 50

2x + 10 + 2x = 50

4x + 10 = 50

4x = 40

x = 10

Answer 2

Answer:x=10

Explanation:

First let's create an equation:

2(x+5)+2x=50

2x+10+2x=50

4x+10=50

4x=40

x=10
