Answer:
A = 450 cm²
Step-by-step explanation:
Since the right triangle is isosceles then the 2 logs are congruent , both 30 cm and at right angles to each other.
The area (A ) of the triangle is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = h = 30 , then
A = × 30 × 30 = × 900 = 450 cm²
answer
their are 4 10.25 and 4 10.50 and 4 11.00 and 2 11.25 and
Step-by-step explanation:
ok so you just need to put those on the line plot
Answer:
Step-by-step explanation:
a). By applying Pythagoras theorem in right triangle ABC,
AC² = AB² + BC²
20² = 16² + BC²
BC =
= 12
Therefore, another leg of the triangular base = 12 cm
Area of the triangular base ABC =
=
= 96 cm²
Volume of a triangular prism = Area of the triangular base × height
960 = 96 × b
b = 10 cm
b). Area of the triangle ABC = 96 cm²
