Answer:
20 ft² - 4ft² = 16 ft²
Step-by-step explanation:
First we solve for the whole rectangle:
Formula: A = ab
side length a = 5 in
side length b = 4 in
diagonal p = q = 6.4031242374328 in
perimeter P = 18 in
area A = 20 in²
Second we deduct the Area of the cutout of the Square
side length a = 2 ft
Area = a² = 4 ft²
Answer:
Rounding to two significant figures the number became
Step-by-step explanation:
Given : Number 8,468
To find : Round this number to two significant figure ?
Solution :
Rounding to two significant figure we have to estimate or round the values in terms of zeros.
Rounding the number to hundreds value,
As 6 is greater than 5 so 4 rounds to 5 and rest became zero.
i.e.
bar means the estimated value.
Therefore, Rounding to two significant figures the number became
