Solve the problem.
-A canvas for a mural is in the shape of a right triangle. Before the mural can be painted, the canvas must be varnished. The base of the mural is 3 meters and the height of the mural is 11 meters. How many cans of varnish
Will you need if each can covers 10 square meters? The formula for the area of a right triangle is A $\mathrm { A } = \frac { 1 } { 2 } \mathrm { bh } .$
A)17 cans of varnish
B)2 cans of varnish
C)4 cans of varnish
D)7 cans of varnish

The area of the mural is calculated using the formula for the area of a right triangle, $A = \frac{1}{2}bh$, where $b = 3$ meters and $h = 11$ meters. Thus, the area is $A = \frac{1}{2} \times 3 \times 11 = 16.5$ square meters. Since each can covers 10 square meters, you would need 2 cans of varnish to cover the 16.5 square meters (the second can is needed to cover the area that exceeds 10 square meters).

Solve the Problem A=12bh.\mathrm { A } = \frac { 1 } { 2 } \mathrm { bh } .A=21​bh.

Solve the Problem $\mathrm { A } = \frac { 1 } { 2 } \mathrm { bh } .$
