Using Pythagorean theorem

Base of one triangle be B

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

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

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

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

Now

$\\ \sf\longmapsto Area=(1)/(2)bh$

$\\ \sf\longmapsto Area=(1)/(2)(7)(26)$

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

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

Total cans

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