Pls help me i need to fill in the boxes that dont have anything in them but i aldo need to fill in the one that says "A="

Answer:
Area is 35
Perimeter is 26
A = hb/2
Step-by-step explanation:
You're given the base (7) and the height (10). The area formula is [tex]\frac{h*b}{2}[/tex].
The area of a triangle is half of the base times the height. 7 * 10 = 70, so 70 is twice the area. Divide it by 2 to get the area (35).
The perimeter is all of the sides added together. 10 + 8 + 7 = 26
