Incline mats, or triangle mats, are offered with different levels of incline to help gymnasts learn basic moves. As the name may

suggest, two sides of the mat are right triangles. If the height of the mat is 21 inches shorter than the length of the mat and the hypotenuse is 6 inches longer than the length of the mat, what is the length of the mat?

<span>Let's assume the mat as a right triangle Taking length of triangle be x so height = x-21 and hypotenuse= x+6 for right triangle we can apply pythagoras theorem so (x+6)^2=x^2+(x-21)^2 expanding we get x^2 + 12 x + 36 = 2 x^2 - 42 x + 441 solving for x we get x=9,45 But for length to be 9 height will be negative So the length of mat will be 45 inches</span>

Mrs. Lopez is designing her garden in the shape of a rectangle. The area of her garden is 2 times greater than the area of the r
scoray [572]

To find the expression for the area of the rectangular garden we will find the area of the rectangle in the picture and then double it.

Area of the garden will be represented by the expression 32s⁵ ft².

Mrs. Lopez is designing her rectangular garden which is 2 times greater than the area of the rectangle shown in the picture.

Dimensions of the rectangle in the picture are 4s³t ft and 8s² ft.

Therefore, area of the rectangle in the picture = Length × Width

                                                                              = 4s³t × 8s²

                                                                              = 32s⁵t ft²

Since, area of the garden is 2 times greater than the area of the rectangle given in the picture.

Therefore, area of the garden = 2(area of the rectangle given in the garden)

                                                  = 2(32s⁵t) square feet.

                                                  = 64s⁵t square feet
