Answer:
270cm²
Step-by-step explanation:
The formula is given as
S = bh × l (s1 + s2 + h)
l = 7cm
h = 5cm
s1 = 12 cm
s2 = 13cm
b = 12 cm
Surface Area = 12 cm × 5 cm × 7 cm(12 cm+ 13 cm+ 5cm)
= 60cm² × 7 cm(30 cm)
= 60cm² + 210 cm²
= 270 cm²
Answer:
220 meter
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Area of square = 275 square meters
Side length (a) = 55 meters
We can calculate the perimeter of square by using following formula,
Perimeter of square = 4a
By putting the value, we get
Perimeter of square = 4 × 55 mt
= 220 meter
Hence, the perimeter of the square is 220 meter.
Part a)
R(x-axis) is the reflection of the original triangle ABC on the x-axis. The new coordinates are given as A' (2, -5), B' (4, -6), and C' (3, -1)
Part b)
R(y=3) is the reflection of the original triangle ABC on the line with equation y=3.
The new coordinates would be A' (2, 1), B' (4, 0), and C' (3, 5)
Part c)
T(-2, 5) is the translation of the original triangle ABC two units left and five units up. The new coordinates would be A'(0, 10), B' (2, 11), and C'(1, 6)
Part d)
T(3, -6) is the translation of the original triangle ABC three units right and six units down. The new coordinates would be A'(5, -1), B'(7, 0), and C'(6, -5)
Part e)
r(90°, 0) is the rotation of the original triangle ABC on the origin by 90° clockwise. The new coordinates would be A'(5, -2), B'(6, -4) and C'(1 -3)
Your answer is 68 have a great day
Area is the area<span> of a flat, or plane figure is the number of unit squares that can be contained within it. The unit square is usually some standard unit, like a square meter, a square foot, or a square inch</span>
