Answer:
0.0X m
Step-by-step explanation:
100 cm = 1 m
According to the question, we have
= 1 m
0.0X = 1 m
Answer:
x = 12
Step-by-step explanation:
equation:
x + 4 = 16
to solve for x, subttract 4 on each side:
x + 4 - 4 = 16 - 4
x = 12
Answer:
Difference in area of the last square and the initial square = 440 cm²
Step-by-step explanation:
Length of the side of a square = 1 cm
Area of the square = (side)² = 1 cm²
Addition of side length every minute = 2 cm
After x minutes length of each side of the square = (1 + 2x) cm
If x = 10 minutes
Length of each side of the square = [1 + 2(10)]
= 21 cm
Area of the square after 10 minutes = (21)²
= 441 cm²
Therefore, difference in area of the last square and area of the initial square
= 441 - 1
= 440 cm²
Step-by-step explanation:
Area of a triangle= 1/2breadth × height
