Question

Do number 6 please!!!

Answer 1

Answer:

1.1768

Step-by-step explanation:

Answer 2

• H=7m
• Sides=A=15m

Using Pythagorean theorem

Base of one triangle be B

$\\ \sf\longmapsto B^2=15^2-7^2$

$\\ \sf\longmapsto B^2=225-49$

$\\ \sf\longmapsto B^2=176$

$\\ \sf\longmapsto B\approx 13$

• Total base=26m

Now

$\\ \sf\longmapsto Area=\dfrac{1}{2}bh$

$\\ \sf\longmapsto Area=\dfrac{1}{2}(7)(26)$

$\\ \sf\longmapsto Area=13(7)$

$\\ \sf\longmapsto Area=91m^2$

• One can covers=20m^2

Total cans

$\\ \sf\longmapsto 91/20=4.5cans$
