Question 620930
Hi, there--
.
STEP I: Calculate the area of the mural.
.
The formula for the area of a triangle is {{{A=(1/2)*b*h}}} where b is the base of the triangle and h is its height. Substitute the values you know into the formula to find the area.
.
{{{A=(1/2)*(3)*(7)}}}
{{{A=10.5}}}
.
The area is 10.5 square meters.
.
Since each can of varnish covers 10 square meters, you will need 2 cans of varnish.
.
Hope this helps!
.
