The width of the rectangle is 1/4 m, which is 3/10 m less than the length. Find its perimeter.

The width of the rectangle is 1/4 m.

The length of the rectangle is 3/10 more than the width, 1/4 + 3/10.

Let’s calculate the length of the rectangle. Let’s bring everything to the same denominator, namely, the common denominator for 4 and 10 will be 40.

1/4 + 3/10 = 10/40 + 12/40 = 22/40 m.

Reduce the fraction by 2 and get 11/20 m.

The perimeter of a rectangle is the sum of all sides or the sum of the length and width times two.

(1/4 + 11/20) ^ 2

(5/20 + 11/20) ^ 2 = 16/20 ^ 2. Multiply only the numerator by 2. We get 16 ^ 2 = 32.

The perimeter of the rectangle is 32/20 m or 20/20 + 12/20 = 1 whole 12/20 or 1 whole 6/10.

answer: 1 whole 6/10.
