Question

after knitting a blanket, monisha washes and stretches it out to the correct size and shape. opposite sides line up with the edges of a rectangular table. she plans to sew a ribbon around the edge of the blanket. how much ribbon will she need? monisha will need of ribbon. (type an integer or a decimal.)

Explanation:

Step1: Identify the shape and formula

The blanket is rectangular, so we use the perimeter formula for a rectangle: \( P = 2(l + w) \), where \( l \) is length and \( w \) is width. Here, \( l = 58 \) in and \( w = 42 \) in.

Step2: Substitute values into the formula

Substitute \( l = 58 \) and \( w = 42 \) into \( P = 2(l + w) \):
\( P = 2(58 + 42) \)

Step3: Simplify the expression

First, calculate the sum inside the parentheses: \( 58 + 42 = 100 \). Then multiply by 2: \( 2 \times 100 = 200 \).

Answer:

200 inches
