5 squares are placed end to end as below (see pic). What is the perimeter of the rectangle formed by the squares?

2b: If x is 2.1, then one side of the rectangle is 2.1, and another is 2.1*5=10.5.  Thus, the perimeter is 2*(2.1+10.5)=2*12.6=25.2.

3: One side of the square with side-length three will not be on the outside, so we have 3*3=9 inches perimeter from the square of side-length 3.  The square of side-length 6 has 3 from the top side missing from the outer perimeter, because it coincides with a side of the square of side-length three.  This square contributes 6*4-3=33 inches.  The total perimeter is 33+9=42 inches.

What is the area of a triangle
Lady bird [3.3K]
The area of a triangle is 1/2 b/h. So what you do is you find base and height, multiply them together and whatever answer you got, you divide by 2. 

Example:
A= 1/2 (b x h)
A= 1/2 (4 x 6)
A= 1/2 (24)
A= 12

Hope this helps!

Hey! pls help me with this question on angles. would really be appreciated. have a nice day.
Neko [114]

Using supplementary angles, it is found that the measures of the angles are given as follows:

  • m<a = 30º.
  • m<b = 90º.

<h3>What are supplementary angles?</h3>

Supplementary angles are two angles whose sum is of 180º.

An interior angle is supplementary with it's exterior angle, hence:

m<a + 150º = 180º -> m<a = 30º.

The sum of the three interior angles of a triangle is of 180º, hence:

30º + m<b + 60º = 180º

90º + m<b = 180º

m<b = 90º.
