What is meaning of irrational exponents.

Here

Step-by-step explanation:

Irrational exponents are non repeating or infinite decimals while rational exponents are rational numbers. The value of an irrational exponent when calculated is approximate in nature while the value of rational exponent is exact.

Solution:

Note that:

Area of trapezoid = Area of rectangle + 2(Area of triangle)

Finding the area of the square.

Area of rectangle = LB=> Area of rectangle = (8)(6)=> Area of rectangle = 48 in²

Finding the area of the 2 triangles.

Area of triangle = 1/2 x Base x Height=> Area of triangle = 1/2 x 4 x 6

Since there are two triangles with the same base and height, we will multiply the area by 2 to cover the other triangle.

=> Area of 2 triangles = 2(1/2 x 4 x 6)=> Area of 2 triangles = 4 x 6=> Area of 2 triangles = 24

Finding the area of the trapezoid.

Area of trapezoid = Area of rectangle + 2(Area of triangle)=> Area of trapezoid = 48 + 24=> Area of trapezoid = 72 in²
