Please help me in math​

Step-by-step explanation:

Let the area of initial square is x, then shaded squares will have area as geometric sequence:

The first term is x, the common ratio is 1/4

Sum of infinite GP is:

By substituting values we get:

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36
