The exponent indicates how many times the number is used as a factor
Answer:
Step-by-step explanation:
suface area of base=1/2×9×7.8=9×3.9=35.1 yd²
lateral surface area=3×1/2×9×10=135 yd²
total surface area=135+35.1=170.1 yd²
i assumed it is an equilateral triangular base.
as √(7.8²+4.5²)=9.0049≈9
Answer:
The formula to find the area of a rectangle is:
b * h = a
where b = base, h = height, and a = area.
The formula to find the area of a triangle is:
(1/2) * b * h = a
where b = base, h = height, and a = area.
They are similar because in both of the formulas, you are multiplying the base by the height. The difference is that in the triangle formula, you have to do an additional step of multiplying by (1/2) to get the area. hope this helps:)
