Pedro is building a playground in the shape of a right triangle. He wants to know the area of the playground to help him decide how much sand to buy. Compose the playground and a matching triangle into a rectangle. What are the dimensions of the​ rectangle? Find the area of the playground. A right triangle has a horizontal base of length 6 yards and a height of 3 and one third yards.

Dimensions of rectangle:

Length =6 yards

Width=3 1/3 yards

Area of right triangle = 10 yd^2

Step-by-step explanation:

The right triangle has base as 6 yards and height as 3 1/3 of yards.

When we match this triangle with another right triangle to make  the rectangle is another right triangle with sides 6 yards and 3 1/3 yards.

I'll upload the file for work.

answer: the area of the parallelogram below is 42 square meters.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
