Hi, there--
.
STEP I: Calculate the area of the mural.
.
The formula for the area of a triangle is A=%281%2F2%29%2Ab%2Ah 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=%281%2F2%29%2A%283%29%2A%287%29
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!
