Area of each triangle
(1/2)(7)(13) = 45.5
Both triangles = 91cm^2
Area of rectangle = 4 * 13 = 52
52cm^2 + 91cm^2 = 143cm^2
The area of the parallelogram is 143cm^2

If the width of a rectangle is 3 and the perimeter is 20 what is the missing side length
I am Lyosha [343]
The formula to find the perimeter of a rectangle is:

P = 2(l + w)

plug in your known values to solve for the unknown

20 = 2(l + 3)
20 = 2l + 6
14 = 2l
14/2 = l
7 = l or l = 7

you can check this by plugging your l value into the equation

P = 2(l + w)
20 = 2(7 + 3)
20 = 2(10)
20 = 20

hope this helps :)

What is the value of a?<br> Step by step please
Flauer [41]
The answer is 15

To find the answer set up an equation like this

a2 + b2 = c2 (2 means squared)

Here we are trying to find the value of a so we know the values of b and c.

a2 + 20(squared) = 25(squared)

20 squared equals 400
25 squared equals 625

a2 + 400 = 625

Subtract 400 from 625 which equals 225.
Now we find the square root or closest square root of 225.
The square root of 225 is 15. 15 x 15 = 225

Estimating Differences of Fractions and Mixed Numbers

Estimating Differences of Fractions and Mixed NumbersRecall that estimation is a method for finding an approximate solution to a problem. Even when you are asked to find an exact ko, estimation is a useful way to get an idea of a reasonable solution to a problem. Once you have found an exact answer, you can check your answer against the estimate.
