Divide.
Answer:
I dont think you have included the whole question please do so
Step-by-step explanation:
Let b and h represent the length of the side of the base and the slant height, respectively. Then the total surface area is
A = b² + 4*(1/2)bh
A = b² +2bh
Substituting the given numbers, you have
336 = 12² +2·12·h
192 = 24h . . . . . . . . . subtract 12² = 144
8 = h . . . . . . . . . . . . . divide by 24
The slant height is 8 inches.
Answer:
The area of that triangle is 28 square inches.
Explanation:
You must choose a height that is perpendicular to the base.
In that case, the height 8 inches is perpendicular to the base 7 inches.
8 inches x 7 inches= 56 inches.
Since the formula for a triangle is base x height divided by 2, we divided 56 by 2
56 divided by 2 = 28
So the area is 28 square inches
