Answer:
Length is 45cm and Breadth is 33cm
Step-by-step explanation:
Perimeter = 156cm
Let the length be x
Breadth = x-12
Perimter = 2(l+b)
156 = 2(x-12+x)
156 = 2(2x-12)
156 = 4x-24
156+25 = 4x
180 = 4x
180÷4 = x
45 = x
Therefore, length is x = 45cm and breadth is x-12 = 45-12 = 33cm
OUR EQUATIONS
LENGTH = x
BREADTH = x-12

Answer:
- w = 8
- x = 8√2
- y = 8√2
- z = 16
Step-by-step explanation:
A 45-45-90 right triangle is isosceles. That means both legs are the same length, and its hypotenuse is √2 times the leg length. You can figure these facts using trigonometry or the Pythagorean theorem, or you can rely on your memory of them.
w = 8 . . . . . . . . . . . same as the leg length shown
x = y = 8√2 . . . . . hypotenuse of smaller triangle; both legs are the same
z = (8√2)√2 = 16 . . . . hypotenuse of larger triangle
The answer would be 7.42

Answer:
2.25 pounds
Step-by-step explanation:
The diagram showing the weight of bags with grapes is shown in the attached file below.
From the diagram; number of bags of grapes that had a weight of pounds or less is:
pounds = 3
pounds = 4
pounds = 1
Thus; the total is = 3+4+1 = 8
However, The total weight of the grapes in the bag that had a weight of pounds or less is :
=
=
=
=
= 2.25 pounds
