Question

The length of a rectangle is twice the width. If the perimeter of the rectangle is 120 meters, its area will be​

Answer 1

Answer:

Step-by-step explanation:

Let the width be x. Then the length would be 2x. Perimeter = 2(l + b)

= 2(2x + x) = 2 x 3x = 6x

So 6x = 120

x = 20

Area = l x b

l = 20 x 2

b = 20

= 40 x 20 = 800

Hope this helps

Answer 2

Step-by-step explanation:

let the width be x

length = 2x

2(2x + x) = 120m

4x + 2x = 120m

6x = 120m

x = 120/6 m

x = 20 m

width = 20m

length = 2(20)m = 40m

area = length × breadth (width)

= 20m × 40m

= 800m²
