Question

Do number 6 please!!!

Answer 1

• 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=(1)/(2)bh`

`\\ \sf\longmapsto Area=(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`
