We can divide into 3 shapes
Area of 1st rectangle: 8*6 = 48 in^2
Area of 2nd rectangle: 10*4 = 40 in^2
Area of 3rd rectangle: 5*4 = 20 in^2
Total area = 48 + 40 + 20 = 108 in^2
The size of the fourth angel = 360 - ( 53 + 127 + 72 ) = 108
Answer:
equilateral: E
scalene: F
isosceles: G
Step-by-step explanation:
equilateral = all sides are equal
scalene = no sides are equal
isosceles = two sides are equal
Answer:
Perímetro = 8.925 metros
Step-by-step explanation:
La formula del perímetro de un rectángulo es:
perímetro = 2(ancho + largo)
en este caso:
p = 2(a+b)
a = 3b/4
b = 2.55m
a = ancho del rectángulo
b = largo del rectángulo
entonces:
sustituyendo el valor de la segunda ecuación
p = 2((3b/4)+b)
p = 2((3b/4)+(4b/4))
p = 2(7b/4)
p = 14b/4
p = 7b/2
p = 7*2.55/2
p = 8.925m
