Find the area of a rectangle if length = 2a + b and breadth = 3a + c
2 answers:
Answer:
6a^2+2ac+3ab+b^2
Step-by-step explanation:
Given
length=2a+b
breadth=3a+c
Now,
Area=?
We know,
Area=l*b
(2a+b)*(3a+c)
2a(3a+c)+b(3a+c)
6a^2+2ac+3ab+b^2
You can use formula (a+b)^2
a^2+2ab+b^2
Step-by-step explanation:
A=l×b
=(2a+b)(3a+c)
=6a²+2ac+3ba+bc
hope it helps.

Hello,
The sum of the angles of a triangle is equal to 180°.
<u>So :</u>
x = 180 - 40 - 55 = 85°
Have a nice day :)
Step-by-step explanation:
The sum of the angles of a triangle is 180°, then:
(x+40)°+(3x-17)°+(2x-5)°=180°
x+40+3x-17+2x-5=180
6x+18=180
6x=162
x=27°
