Use the correct order of operations to evaluate the following expression:(5+4).5+3.3

Mathematics
1 answer:
horsena [70]2 years ago
7 0

Answer:

For any mathematical expression follow the BODMAS rule which states that we should calculate the Brackets first (2 + 4 = 6), then the Orders (52 = 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43).

Step-by-step explanation:

(5+4) × 5 + 3.3

Bracket open = 9

Since there is no division, so multiply 9×5, which is 45

Then add, 45+3.3

Answer= 48.3

The area of a square piece of land is 784metersquared .What is the perimeter​
Marta_Voda [28]

Answer:

112 m

Step-by-step explanation:

The area (A) of a square is

A = s² ( s is the length of side )

Here A = 784 , then

s² = 784 ( take the square root of both sides )

s = \sqrt{784} = 28

Then

perimeter = 4s = 4 × 28 = 112 m
