Answer:

P = 25.6 feet

Step-by-step explanation:

Given that,

Rectangle A and B have the same Area.

The area of a rectangle is given by :

A = lb

l_Ab_A=l_Bb_B

We have,

l_A=7\ m, b_A=4\ m, b_B=10\ m

So,

l_B=\dfrac{l_Ab_A}{l_B}\\\\l_B=\dfrac{7\times 4}{10}\\\\l_B=2.8\ m

The perimeter of rectangle B,

P=2(l_B+b_B)\\\\=2(2.8+10)\\\\=25.6\ ft

So, the perimeter of rectangle B is equal to 25.6 feet.

(6+3)4 I don't understand what it means I really need some help​
Over [174]

Answer:

36

Step-by-step explanation:

Hullo :D

If you're having trouble understanding, you might not understand the Order of Operations.

P - Parenthesis. Solve what's inside the Parenthesis first

E - Exponents. Solve for Exponents second.

M - Multiply. Multiply numbers third. (left - to - right with division, too)

D - Divide. Divide fourth. It is interchangeable with multiplication, as well.

A - Addition. Add fifth.

S - Subtract sixth. It is interchangeable with Addition, as well.

With that in mind, all we need to do is identify these types in the equation:

(6+3)4

We see parenthesis. We will solve them first according to the Order of Operations:

6 + 3 = 9.

(9)4

We see multiplication. We solve them next according to the Order of Operations:

9 × 4 = 36.

Thus, the final answer is \boxed{36}.

Hope this helps!
