Answer:
<u>202 square inches</u>
Step-by-step explanation:
We can break this shape down into two rectangles, one with the dimensions of 13in by 4in and the other by 15in and 10in. Now we can find the area of both shapes by multiplying the sides together so the 13in by 4in shape has the area of 52 square inches and the 15in by 10in shape has the area of 150 square inches. Now, add the two areas together and the total area of the whole shape is 202 square inches.
Based on the dimensions of the regular pentagon, the approximate area can be found to be 342 cm².
<h3>How to solve for approximate area?</h3>
The area of the pentagon can be found by the formula:
= 5 x 1/2 x Length of pentagon x apothem of pentagon
The apothem is:
= √(12² - (14.1/2)²)
= 9.7
The approximate area of the pentagon is therefore:
= 5 x 1/2 x 14.1 x 9.7
= 342 cm²

Angles of a triangle add up to 180 degrees and then we take away the right angle
180-90=90
5x+5x=10x
90/10=9
x=9
