Answer:
The perimeter of the Rectangle JKLM is 32 unit.
Step-by-step explanation:
Consider the provided coordinates.
Rectangle JKLM: J(-3, 8), K(-3,-1), L(4, -1), M(4,8)
First plot the points as shown in figure:
The required figure is shown below:
Now find the distance between JK by using the distance formula.
Therefore, the length of JK is 9 unit.
Now find the length of the side JM
Therefore, the length of JM is 7 unit.
The perimeter of rectangle is: 
Therefore,
Hence, the perimeter of the Rectangle JKLM is 32 unit.
Answer:
7=2+r
Step-by-step explanation:
basic algebra, can u mark brainliest answer please?
0.625 dozen
1/12 x 7.5
= 0.625
If a triangle has sides of 7 cm and it is an equilateral you can draw a line right down the middle to form two congruent triangles.
These smaller triangles have a hypotenuse of 7cm and a base of 3.5 cm (7/2)
To work out the height, use Pythagoras’ theorem.
a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the other two sides
7^2 - 3.5^2 = 36.75
Square root answer
= 6.06 cm
That’s the height of the triangle
Area of a triangle is base x height divided by 2
So 7 x 6.06 = 42.43…
/2
= 21.2 cm^2 to one d.p
