Question

The perimeter of a rectangle is 56 m. The width of the rectangle is 4 m less than the length. Find the length and width of the rectangle. Full Solution and Answer pls

Answer 1

Answer:

Length = 16m

Width = 12m

Step-by-step explanation:

Let Length of the rectangle = L

Let width of the rectangle = L – 4m

So now, Perimeter of a rectangle = 56m

=> 2(length + breadth) = 56m

=> 2(L + L – 4m) = 56m

=> 2(2L – 4m) = 56m

=> 4L – 8m = 56m

=> 4L = 56m + 8m

=> 4L = 64m

=> L = 64m ÷ 4

=> L = 16m

And, Width = L – 4m

= 16m – 4m

= 12m
