Answer:
Step-by-step explanation:
Triangle:
Base = 4 units
Height = 3 units {perpendicular height}
= 6 square units
Rectangle:
To find the area count the number of squares. Number of square = 6
Area = 6 square units
or You can find the area of the rectangle as bellow also
Length = 3 units
Width = 2 units
Area = length*width
= 3*2
= 6 square units
Both the triangle and rectangles has the same area 6 square units

Answer:
53 lies between 7.2² and 7.3²
Step-by-step explanation:
Estimating a root to the nearest tenth can be done a number of ways. The method shown here is to identify the tenths whose squares bracket the value of interest.
You have answered the questions of parts 1 to 3.
__
<h3>4.</h3>You are given that ...
7.2² = 51.84
7.3² = 53.29
This means 53 lies between 7.2² and 7.3², so √53 lies between 7.2 and 7.3.
53 is closer to 7.3², so √53 will be closer to 7.3 than to 7.2.
7.3 is a good estimate of √53 to the tenths place.

<em>Additional comment</em>
For an integer n that is the sum of a perfect square (s²) and a remainder (r), the square root is between ...
s +r/(2s+1) < √n < s +r/(2s)
For n = 53 = 7² +4, this means ...
7 +4/15 < √53 < 7 +4/14
7.267 < √53 < 7.286
Either way, √53 ≈ 7.3.
