Question

4 in.

Answer 1

Answer:

305.12 square inches

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The area of the window is equal to the area of a rectangle, plus the area of two quarter circles plus the area of the smaller square between the two upper corners

so

Find the area of rectangle

$A=(12)(26-4)=264\ in^2$

Find the area of the two quarter circle

$A=2[\frac{1}{4}(3.14)(4^2)]$

$A=25.12\ in^2$

Find the area of the smaller square between the two upper corners

$A=(12-8)(4)=4^2=16\ in^2$

The total area is equal to

$A=264+25.12+16=305.12\ in^2$
