Answer:
45.8
Step-by-step explanation:
Say the number Malachy was thinking of is <em>x</em>.
Doubling it gives 2x, which we see also equals 91.6. Set these equal to each other:
2x = 91.6
To solve, we divide both sides by 2 and get x = 45.8, which is our answer.
A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles. To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.
Step-by-step explanation:
c²=24²+45²=2601
so c=51
