Answer:

Blue fabric (triangles) = 27 m²

Green fabric (square) = 9 m²

Step-by-step explanation:

✔️Blue fabric (triangles) = 4(area of triangular face)

= 4(½*b*h)

b = 3 m

h = 4.5 m

= 4(½*3*4.5)

= 27 m²

✔️Green fabric (square) = area of the square base

= s²

s = 3

Area = 3²

= 9 m²

Lucy spends 4 hours a week babysitting. Her sister Lily spends seven eighths as much time babysitting. Does Lily babysit for mor

olganol [36]

Answer:

Lily babysit for <u>less than 4 hours</u>.

Step-by-step explanation:

Given:

Lucy spends in a week babysitting for 4 hours.

Lily spends seven-eighths of 4 hours.

Now, to find whether Lily babysit for more than 4 hours or less than that.

Number of hours Lucy babysit = 4 hours.

So, to get the hours Lily babysit:

$\frac{7}{8}\ of\ 4\ hours.$

$=\frac{7}{8}\times 4\\\\=\frac{28}{8} \\\\$

<em>On simplifying we get:</em>

$=\frac{7}{2} \\\\=3\frac{1}{2}\ hours.$

<u><em>Thus, Lily spends </em></u> $3\frac{1}{2}\ hours$ <u><em> for babysitting which is less than 4 hours.</em></u>

Therefore, Lily babysit for less than 4 hours.
