Answer:
8 pieces of string
Step-by-step explanation:
Given that :
Total yards of string = 4
Length in yd of each string = 1/2 yards
Number of pieces of string Ms. Cole has :
Total. Yards / length in yard of each string
4 / (1/2)
4 * (2 /1)
= 8/1
= 8 pieces of string.
To find the shaded area in an image first calculate the total area of the figure and then subtract the white area from this total.
<h3>How to find the area of a shaded area?</h3>
- Determine the total area of the figure, in this case, the are of the rectangle that contains the triangle and the semicircle.
- Calculate the area of the white region.
- Substract the non-shaded area to the total area.
<h3>How to find out the area of different shapes?</h3>
- Rectangle: side x side = 2 x 4 = 8 square feet
- Isosceles triangle = 1/2 base x height
- Semicirle = 1/2 (π x r^2)
Note: This question is incomplete because the image of the shaded regions is not provided; due to this, the answer is based on general knowledge.
